I would like to replace the text in a google doc. At the moment I have place markers as follows
Invoice ##invoiceNumber##
I replace the invoice number with
body.replaceText('##invoiceNumber##',invoiceNumber);
Which is fine but I can only run the script once as obviously ##invoiceNumber## is no longer in the document. I was thinking I could replace the text after Invoice as this will stay the same, appendParagraph looks like it might to the trick but I can't figure it out. I think something like body.appendParagraph("Invoice") would select the area? Not sure how to append to this after that.
You could try something like this I think:
body.replaceText('InvoiceNumber \\w{1,9} ','InvoiceNumber ' + invoicenumber);
I don't know how big your invoice numbers are but that will except from 1 to 9 word characters preceeded by a space and followed by a space. That pattern might have to be modified depending upon your textual needs.
Word Characters [A-Za-z0-9_]
If your invoice numbers are unique enough perhaps you could just replace them.

I have a bunch of records in a QuickBase table that contain a rich text field. In other words, they each contain some paragraphs of text intermingled with HTML tags like <p>, <strong>, etc.
I need to migrate the records to a new table where the corresponding field is a plain text field. For this, I would like to strip out all HTML tags and leave only the text in the field values.
For example, from the below input, I would expect to extract just a small example link to a webpage:
<p>just a small <a href="#">
example</a> link</p><p>to a webpage</p>
As I am trying to get this done quickly and without coding or using an external tool, I am constrained to using Quickbase Pipelines' Text channel tool. The way it works is that I define a regex pattern and it outputs only the bits that match the pattern.
So far I've been able to come up with this regular expression (Python-flavored as QB's backend is written in Python) that correctly does the exact opposite of what I need. I.e. it matches only the HTML tags:
/(<[^>]*>)/
In a sense, I need the negative image of this expression but have not be able to build it myself.
Your help in "negating" the above expression is most appreciated.
Assuming there are no < or > elsewhere or entity-encoded, an idea using a lookbehind.
(?:(?<=>)|^)[^<]+
See this demo at regex101
(?:(?<=>)|^) is an alternation between either ^ start of the string or looking behind for any >. From there [^<]+ matches one or more characters that are not < (negated character class).
I want to create a pattern for an HTML input field that needs to have at least 10 numbers in it and may also have spaces and a plus sign on top of that, but it's not required.
It's important that numbers and spaces can be mixed though. Also, the whole field can only have 17 characters all in all.
I'm not sure if it's even possible. I started doing something like that:
pattern="[0-9+\s]{10,17}*"
But like this, it's not guaranteed that there are at least 10 numbers.
Thanks in advance! Hope the question doesn't exist already, I looked but couldn't find it.
You can use
pattern="(?:[+\s]*\d){10,17}[+\s]*"
The regex matches
(?:[+\s]*\d){10,17} - ten to seveteen occurrences of zero or more + or whitespaces and then a digit
[+\s]* - zero or more + or whitespaces.
Note the pattern is anchored by default (it is wrapped with ^(?: and )$), so nothing else is allowed.
How does one append all lines in a SQL query with text?
In order to add something to the front of my lines of code I can use Alt+Shift down the left side and type something to change
example-1
example-12
example-123
example-1234
example-12345
to
a.example-1
a.example-12
a.example-123
a.example-1234
a.example-12345
but if I want to add something to the right side, it turns out like this
a.example-1*
a.example-1*
a.example-1*3
a.example-1*34
a.example-1*345
when i want it to look like this
a.example-1*
a.example-12*
a.example-123*
a.example-1234*
a.example-12345*
So, how do I do this? Is it possible to append all lines with something with Alt+Shift or is there another method?
*Edit example
To clarify, I need to edit the text in my SQL code, not the text within my tables and such. Ex.:
SELECT TOP 1000
[day]
,[workout_name]
,[reps]
FROM [tom].[dbo].[workout_routine]
but instead of having the commas at the beginning of [day], [workout_name], let's say I need them at the end, like:
SELECT TOP 1000
[day],
[workout_name],
[reps]
FROM [tom].[dbo].[workout_routine]
Because Alt+Shift works and aligns at any column of text, but I need to know if there is a way to be able to add something to the end of lines of differing lengths.
There is a Concat function in mysql.
Select concat(row, ' text after row') from table
If you're looking to modify a script, you can use Regex to replace $ which represents the end of line character. So if you were in Notepad++, you can do a find and replace for $. Make sure you allow Regular expression in the search mode.
I am making a small online database that is accessible through the form of checkboxes for download. I was wondering if there was some way to list all of the filenames available for download in Sublime Text 2 and insert the same code around each filename?
Everything is functional, it would just save me a lot of repetitive copy and pasting if there is a faster way to do this.
Use SublimeText Find & Replace. Click the Regex button (it looks like a * to the left of the search box)
In the Find box, insert: (^.*$)
In the replace box: [yourcode]$1[yourcode]
Where [yourcode] is what you want to insert into the box.
So, if you want to make them all <li> then your replace box would be:
<li>$1</li>
Remember to use escape \ characters where they are needed, in case you need to insert restricted characters.
^ - beginning of a new line.
. - wildcard
* - any number of the previous character in the sequence (in this case a wildcard, so any text)
$ - the end of a line
() - denotes a block, it's how the $1 knows what text to put in it's place.
Sublime Text Search and Replace
Use search/replace on a text editor with regular expressions.
^ and $ represent the beginning and end of a line - thus allowing you to easily surround each line with the appropriate text.
Sometimes you can copy the newline character (as in copy the end of one line to the beginning of the next line), and replace that with whatever text you need.
You could always use the regular expression search / replace feature in Notepad++.
I would like to make a sort of hash key out of a text (in my case html) that would match/compare to the hash of other similar text
ex of matching texts:
"2012/10/01 This is my webpage #1"+ 100k_of_same_text + random_words_1 + ..
"2012/10/02 This is my webpage #2"+ 100k_of_same_text + random_words_2 + ..
...
"2012/10/02 This is my webpage #2"+ 100k_of_same_text + random_words_3 + ..
So far I've thought of removing numbers and tags but that wold still leave the random words.
Is there anything out there that dose this?
I have root access to the server so I can add any UDF that is necesare and if needed I can do the processing in c or other languages.
The ideal would be a function like generateSimilarHash(text) and an other function compareSimilarHashes(hash1,hash2) that would return the procent of matching text.
Any function like compare(text1,text2) would not work as in my case as I have many pages to compare (~20 mil at the moment)
Any advice is welcomed!
UPDATE:
I'm refering to ahash function as it is described on wikipedia:
A hash function is any algorithm or subroutine that maps large data
sets of variable length to smaller data sets of a fixed length.
the fixed length part is not necessary in my case.
It sounds like you need to utilize a program like diff.
If you are just trying to compare text a hash is not the way to go because slight differences in input cause total and complete differnces in output. (Thus the reason why they are used to encode passwords, and secure text). Character difference programs are pretty complicated, unless you really are interested in how they work and are trying to write your own I would just use a solution like the one that is shown here using sdiff to get a percentage.

You could use some sort of Levenshtein distance algoritm. this works for small pieces of text, but I'm rather sure that something similar can be applied to large chunks of text.

I've found out that tag order in webpages can create a very distinctive pattern, that remains the same even if portions of text / css / script change. So I've made a string generated by the tag order (ex: html head meta title body div table tr td span bold... => "hhmtbdttsb...") and then I just do exact matches between these strings. I can even apply the Levenshtein distance algorithm and get accurate results.
If I didn't have html, I would have used the punctuation/end-lines for splitting, or something similar.
