Character encoding issue when using Google Apps Script to extract data from web page - google-apps-script

I have written a script using Google Apps Script to extract text from a web page into Google Sheets. I only need this script to work with a specific web page, so it does not need to be versatile. The script works almost exactly as I want it to except that I have run into a character encoding problem. I am extracting both Hebrew and English text. The meta tag in the HTML has charset=Windows-1255. The English extracts perfectly, but the Hebrew displays as black diamonds containing a question mark.
I found this question that says to pass the data into a blob then use the getDataAsString method to convert to another encoding. I tried converting to different encodings and got different results. UTF-8 displays the black diamonds with question marks, UTF-16 displays Korean, ISO 8859-8 returns an error and says it's not a valid parameter, and the original Windows-1255 displays one Hebrew character but a bunch of other gibberish.
However, I am able to copy and paste the Hebrew text into Google Sheets manually and it displays correctly.
I have even tested passing Hebrew directly from Google Apps Script code like so:
function passHebrew() {
return "וַיְדַבֵּר";
}
This displays the Hebrew text properly on Google Sheets.
My code is as follows:
function parseText(book, chapter) {
//var bk = book;
//var ch = chapter;
var bk = '04'; //hard-coded for testing purposes
var ch = '01'; //hard-coded for testing purposes
var url = 'http://www.mechon-mamre.org/p/pt/pt' + bk + ch + '.htm';
var xml = UrlFetchApp.fetch(url).getContentText();
//I had to "fix" these xml errors for XmlService.parse(xml) below
//to function.
xml = xml.replace('<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">', '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "">');
xml = xml.replace('<LINK REL="stylesheet" HREF="p.css" TYPE="text/css">', '<LINK REL="stylesheet" HREF="p.css" TYPE="text/css"></LINK>');
xml = xml.replace('<meta http-equiv="Content-Type" content="text/html; charset=Windows-1255">', '<meta http-equiv="Content-Type" content="text/html; charset=Windows-1255"></meta>');
xml = xml.replace(/ALIGN=CENTER/gi, 'ALIGN="CENTER"');
xml = xml.replace(/<BR>/gi, '<BR></BR>');
xml = xml.replace(/class=h/gi, 'class="h"');
//This section is the specific route to the table in the page I want
var document = XmlService.parse(xml);
var body = document.getRootElement().getChildren("BODY");
var maintable = body[0].getChildren("TABLE");
var maintablechildren = maintable[0].getChildren();
//This creates a two-dimensional array so that I can store the Hebrew
//in the first column and the English in the second column
var array = new Array(maintablechildren.length);
for (var i = 0; i < maintablechildren.length; i++) {
array[i] = new Array(2);
}
//This is where the table gets parsed into the array
for (var i = 0; i < maintablechildren.length; i++) {
var verse = maintablechildren[i].getChildren();
//This is where the encoding problem occurs.
//I originally tried verse[0].getText() but it didn't work.
array[i][0] = Utilities.newBlob(verse[0].getText()).getDataAsString('UTF-8');
//This array receives the English text and works fine.
array[i][1] = verse[1].getText();
}
return array;
}
What am I overlooking, misunderstanding, or doing wrong? I don't have a very good understanding of how encoding works so I don't understand why converting it to UTF-8 isn't working.

Your problem occurs before the lines you've commented as an encoding problem: because the default encoding for UrlFetchApp is munging the unicode text from the start.
You should use the variation of the .getContentText() method that Returns the content of an HTTP response encoded as a string of the given charset. For your case:
var xml = UrlFetchApp.fetch(url).getContentText("Windows-1255");
That should be all you need to change, although the blob() work-around is no longer needed. (It's harmless, though.) Other comments:
The logical OR operator (||) is very helpful for setting default values. I've tweaked the first few lines to enable testing but still let the function operate normally with arguments.
The way you're setting up an empty array before populating it with strings is Bad JavaScript; it's complex code that isn't needed, so toss it. Instead, we'll declare the array Array, then push() rows onto it.
The .replace() functions can be reduced with more clever RegExp use; I've included the URLs for demos of the really tricky ones.
There were \n newline characters in the text which I guessed were unnecessary for your purposes, so added a replace() for them as well.
Here's what you're left with:
function parseText(book, chapter) {
var bk = book || '04'; //hard-coded for testing purposes
var ch = chapter || '01'; //hard-coded for testing purposes
var url = 'http://www.mechon-mamre.org/p/pt/pt' + bk + ch + '.htm';
var xml = UrlFetchApp.fetch(url).getContentText("Windows-1255");
//I had to "fix" these xml errors for XmlService.parse(xml) below
//to function.
xml = xml.replace(/(<!DOCTYPE.*EN")>/gi, '$1 "">')
.replace(/(<(LINK|meta).*>)/gi,'$1</$2>') // https://regex101.com/r/nH3pU8/1
.replace(/(<.*?=)([^"']*?)([ >])/gi,'$1"$2"$3') // https://regex101.com/r/eP7wO7/1
.replace(/<BR>/gi, '<BR/>')
.replace(/\n/g, '')
//This section is the specific route to the table in the page I want
var document = XmlService.parse(xml);
var body = document.getRootElement().getChildren("BODY");
var maintable = body[0].getChildren("TABLE");
var maintablechildren = maintable[0].getChildren();
//This is where the table gets parsed into the array
var array = [];
for (var i = 0; i < maintablechildren.length; i++) {
var verse = maintablechildren[i].getChildren();
//I originally tried verse[0].getText() but it didn't work.** It does now!
var hebrew = verse[0].getText();
//This array receives the English text and works fine.
var english = verse[1].getText();
array.push([hebrew,english]);
}
return array;
}

Parsing Special characters in google apps script

I am trying to pars a xml file into new google users,
This xml file contains the usernames made from the front and last name of the specified user. However when creating users it generates an error becaus some names have ilegal caracters in them.
These ilegal caracts are stuff like
ï ë é í
etc
Now i made a function which loops trough every username from the xml file and checks every caracter if it is one of the ilegal caracters and replaces them with there "normal" counterpart (fe) ä --> a.
but is there a way to automaticly convert all special caracters to there normal counterpart?
so i am searching for a function with the interface var
Username = ConvertUserName(UserNameWithIlegalCaracters);
now i am looping trough the caracters in the username and checking for each of them if they are (by refering to a list) if they are ilegal caracters and replacing them.
However now the program will fail if there are any ilegal caracters added to the names which are not in my list.
Anytime you're looking for an answer about how to do something in Google Apps Script, but it has little-or-nothing to do with Google services, check javascript first.
Search javascript diacritics: 68 results
You'll most likely find the function you need in Remove accents/diacritics in a string in JavaScript, which compares the performance of several options.
Below is the one that was fastest. To use, var userName = removeDiacritics(userNameWithIllegalCharacters);
var defaultDiacriticsRemovalap = [

How do I find the page number/number of pages in a document?

I want to create a new document based on a template and need to know when my insertion or append results in a new page in the final printed output is there any property/attribute eg number of pages that can be used for this?
I've search this a lot in the past and I don't think there's any property or any other way to know page info.
The solution I use is to insert page breaks on my template or via the script, using my own knowledge of how my template works, i.e. how much space it takes as I iterate, etc.
And then I know which page I am by counting the page breaks.
Anyway, you could an enhancement request on the issue tracker.
One way to get total number of pages:
function countPages() {
var blob = DocumentApp.getActiveDocument().getAs("application/pdf");
var data = blob.getDataAsString();
var re = /Pages\/Count (\d+)/g;
var match;
var pages = 0;
while(match = re.exec(data)) {
Logger.log("MATCH = " + match[1]);
var value = parseInt(match[1]);
if (value > pages) {
pages = value;
}
}
Logger.log("pages = " + pages);
return pages;
}

Losing leading 0s when string converts to array

I have a textInput control that sends .txt value to an array collection. The array collection is a collection of US zip codes so I use a regular expression to ensure I only get digits from the textInput.
private function addSingle(stringLoader:ArrayCollection):ArrayCollection {
arrayString += (txtSingle.text) + '';
var re:RegExp = /\D/;
var newArray:Array = arrayString.split(re);
The US zip codes start at 00501. Following the debugger, after the zip is submitted, the variable 'arrayString' is 00501. But once 'newArray' is assigned a vaule, it removes the first two 0s and leaves me with 501. Is this my regular expression doing something I'm not expecting? Could it be the array changing the value? I wrote a regexp test in javascript.
<script type="text/javascript">
var str="00501";
var patt1=/\D/;
document.write(str.match(patt1));
</script>
and i get null, which leads me to believe the regexp Im using is fine. In the help docs on the split method, I dont see any reference to leading 0s being a problem.
**I have removed the regular expression from my code completely and the same problem is still happening. Which means it is not the regular expression where the problem is coming from.
Running this simplified case:
var arrayString:String = '00501';
var re:RegExp = /\D/;
var newArray:Array = arrayString.split(re);
trace(newArray);
Yields '00501' as expected. There's nothing in the code you've posted that would strip leading zeros. You may want to dig around a bit more.
This smells suspiciously like Number coercion: Number('00501') yields 501. Read through the docs for implicit conversions and check if any pop up in your code.
What about this ?
/^\d+$/
You can also specify exactly 5 numbers like this :
/^\d{5}$/
I recommend just getting the zip codes instead of splitting on non-digits (especially if 'arrayString' might have multiple zip codes):
var newArray:Array = [];
var pattern:RegExp = /(\d+)/g;
var zipObject:Object;
while ((zipObject = pattern.exec(arrayString)) != null)
{
newArray.push(zipObject[1]);
}
for (var i:int = 0; i < newArray.length; i++)
{
trace("zip code " + i + " is: " + newArray[i]);
}

JSFL: convert text from a textfield to a HTML-format string

I've got a deceptively simple question: how can I get the text from a text field AND include the formatting? Going through the usual docs I found out it is possible to get the text only. It is also possible to get the text formatting, but this only works if the entire text field uses only one kind of formatting. I need the precise formatting so that I convert it to a string with html-tags.
Personally I need this so I can pass it to a custom-made text field component that uses HTML for formatting. But it could also be used to simply export the contents of any text field to any other format. This could be of interest to others out there, too.
Looking for a solution elsewhere I found this:
http://labs.thesedays.com/blog/2010/03/18/jsfl-rich-text/
Which seems to do the reverse of what I need, convert HTML to Flash Text. My own attempts to reverse this have not been successful thus far. Maybe someone else sees an easy way to reverse this that I’m missing? There might also be other solutions. One might be to get the EXACT data of the text field, which should include formatting tags of some kind(XML, when looking into the contents of the stored FLA file). Then remove/convert those tags. But I have no idea how to do this, if at all possible. Another option is to cycle through every character using start- and endIndex, and storing each formatting kind in an array. Then I could apply the formatting to each character. But this will result in excess tags. Especially for hyperlinks! So can anybody help me with this?
A bit late to the party but the following function takes a JSFL static text element as input and returns a HTML string (using the Flash-friendly <font> tag) based on the styles found it its TextRuns array. It's doing a bit of basic regex to clear up some tags and double spaces etc. and convert /r and /n to <br/> tags. It's probably not perfect but hopefully you can see what's going on easy enough to change or fix it.
function tfToHTML(p_tf)
{
var textRuns = p_tf.textRuns;
var html = "";
for ( var i=0; i<textRuns.length; i++ )
{
var textRun = textRuns[i];
var chars = textRun.characters;
chars = chars.replace(/\n/g,"<br/>");
chars = chars.replace(/\r/g,"<br/>");
chars = chars.replace(/ /g," ");
chars = chars.replace(/. <br\/>/g,".<br/>");
var attrs = textRun.textAttrs;
var font = attrs.face;
var size = attrs.size;
var bold = attrs.bold;
var italic = attrs.italic;
var colour = attrs.fillColor;
if ( bold )
{
chars = "<b>"+chars+"</b>";
}
if ( italic )
{
chars = "<i>"+chars+"</i>";
}
chars = "<font size=\""+size+"\" face=\""+font+"\" color=\""+colour+"\">"+chars+"</font>";
html += chars;
}
return html;
}

Extracting links and twitter replies from a string

I am getting a string from Twitter into my Actionscript which is a unformatted string. I want to be able to extract any links and or any #replies from the string, then display it in htmlText.
So far I have this
var txt:String = "This is just some text http://www.thisisawebsite.com and some more text via #sumTwitter";
var twitterText:String = txt.slice(txt.indexOf("#"),txt.indexOf(" ",txt.indexOf("#")));
var urlText:String = txt.slice(txt.indexOf("http"),txt.indexOf(" ",txt.indexOf("http")));
var newURL:String = ""+urlText+"";
var arr:Array = txt.split(urlText);
var newString:String = arr[0] + newURL + arr[1];
var txtField:TextField = new TextField();
txtField.width = 500;
txtField.htmlText = newString;
addChild(txtField);
This is fine for extracting links, which finish with a space. But what if, like the #sumTwitter, it finishes at the end of the string. And also what if there are multiple links or #'s, is the best way to put it in a while loop?
Regular expressions are the best option for what you want, I think.
Check Grant Skinner's RegExr. You could write and test your own RegExp there, which is very convenient. But you also can find a lot of useful ready-to-use regexps created by different users. Check out the "community" tab in the right panel. There, search by some meaningful keywords like "twitter" and "url" and you'll get a good number of options.
For example,
Grab urls:

Capture twitter usernames:
