I have ran into a bit of problem. Originally, I have the following input of the format:
12345 apple
12 orange
I saved the first column as $num and second column as $fruit. I want the output to look like this (see below). I would like for the output to align as if the $num are of all the same length. In reality, the $num will consists of variable-length numbers.
12345 apple
12 orange
As suggested, I use the following code:
$line = sprintf "%--10s %-20s", $num, $fruit;
This solution works great in command-line display, but this formatting is not retained when I try to display this via HTML. For example..
print "<html><head></head><body>
$line
</body></html>";
This produces the same output as the original before formatting. Do you guys have a suggestion as to how I can retain the sprintf formatting in html web-based display? I try to pad the $num with whitespaces, but the following code doesn't seem to work for me.
$num .= (" " x (10 - length($num)));
Anyways, I would appreciate any suggestions. Thanks!
HTML ignores extra whitespace. And the fact that it's probably displaying with a proportional font means it wouldn't line up even if the extra spaces were there.
The easy option is to just surround the text with <pre> tags, which will display by default with a monospace font and whitespace preserved. Alternatively, you can have your code generate an HTML table.
HTML compresses all consecutive spaces down to one space. If you want your output to be lined up like a table, you have to actually put the values in an HTML table.
The 'pre' in <pre> means preformatted, which exactly describes the output of a sprintf() statement. Hence the suggestion from friedo and I suspect, others.

We are using s:property tag to display string value on struts 2.
<s:property value="stringValue"/>
If "stringValue" has multiple spaces then it is showing only 1 space instead of exact text.
Ex: String stringValue ="Hello World, Welcome";
Output: Hello World, Welcome.
Here string text has two space in between but on application it is displaying only 1 space.
I have tried to use escapeHtml as false but same issue.
What is wrong with this tag?

Nothing is wrong with the tag.
HTML treats multiple whitespaces as a single whitespace; that's just the way HTML is.
If you want to explicitly have multiple spaces you'll need to convert them to entities. There are a zillion ways to do that.
Question is very simple but I am not found solution yet - probably it is not possible or very hard to find since it is very trivial.
Question is how to avoid adding spaces in formatted HTML after new line - especially in list of values.
First example see example:
1, 2
It produces required HTML like this:
1, 2
Now another example which not works:
1
,
2
It produces invalid HTML like this:
1 , 2 required is 1, 2
How to achieve same result as in first example but using multiline text layout - I know that we could do it in one line but want to do in many lines to simplify program code (not HTML).
It works as defined: in normal content, a newline is equivalent to a space. There is no way to change this principle in HTML. Just divide you content into lines so that the principle works for you, not against you. That is, break a line only at a point where a space is OK.
I need there to be two spaces after every period in every sentence in our entire site (don't ask).
One way to do it is to embark on manually adding a   after every single period. This will take several hours.
We can't just find and replace every period, because we have concatenations in PHP and other cases where there is a period and then a space, but it's not in a sentence.
Is there a way to do this...and everything still work in Internet Explorer 6?
[edit] - The tricky part is that in the code, there are lines of PHP that include dots with spaces around them like this:
<?php echo site_url('/css/' . $some_name .'.css');?>
I definitely don't want extra spaces to break lines like that, so I would be happy adding two visible spaces after each period in all P tags.
As we all know, HTML collapses white space, but it only does this for display. The extra spaces are still there. So if the source material was created with two spaces after each period, then some of these substitution methods that are being suggested can be made to work reliably - search for "period-space-space" and replace it with something more suituble, like period-space- . Please note that you shouldn't use because it can prevent proper wrapping at margins. (If you're using ragged right, the margin change won't be noticeable as long as you use the the nbsp BEFORE the space.)
You can also wrap each sentence in a span and use the :after selector to add a space and format it to be wide with "word-spacing". Or you can wrap the space between sentences itself in a span and style that directly.
I've written a javascript solution for blogger that does this on the fly, looks for period-space-space, and replaces it with a spanned, styled space that appears wider.
If however your original material doesn't include this sort of thing then you'll have to study up on sentence boundary detection algorithms (which are not so simple), and then modify one to also not trip over PHP code.
You might be able to use the JavaScript split method or regex depending on the scope of the text.
Here's the split method:
var el = document.getElementById("mydiv");
if (el){
el.innerText = el.innerText.split(".").join(".\xA0 ");
}
Test case:
Hello world.Insert spaces after the period.Using the split method.
Result:
Hello world. Insert spaces after the period. Using the split method.
Have you thought using output buffer? ob_start($callback)
Not tested, but if you'll stick this before any output (or betetr yet, offload the function):
<?php
function processDots($buffer)
{
return (str_replace(".", ". ", $buffer));
}
ob_start("processDots");
?>
and add this to end of input:
<?php ob_end_flush(); ?>
Might just work :)
If you're not opposed to a "post processing"/"javascript" solution:
var nodes = $('*').contents().map(function(a, b) {
return (b.nodeType === Node.TEXT_NODE ? b : null);
});
$.each(nodes, function(i,node){
node.data = node.data.replace(/(\.\s)/g, '.\u00A0\u00A0');
});
Using jQuery for the sake of brevity, but not required.
p.s. I saw your comment about not all periods and a space are to be treated equal, but this is about as good as it gets. otherwise, you're going to need a lot better/more bullet-proof approach.
Incorporate something like this into your PHP file:
<?php if (preg_match('/^. [A-Z]$/' || '/^. [A-Z]$/')) { preg_replace('. ', '. '); } ?>
This allows you to search for the beginning of each new sentence as in .spacespaceA-Z, or .spaceA-Z and then replaces that with . space. [note: Capital letter is not replaced]

If I want to preserve the line breaks when displaying this field on a webpage, is the standard solution to write a script to replace '\n\r' with a br HTML tag or is there a better way?
Thanks!
Assuming PHP here...
nl2br() adds in <br /> for every \n. Don't forget to escape the content first, to prevent XSS attacks. See below:
<?php echo nl2br(htmlspecialchars($content)); ?>
HTML is a markup language. Regardless of how many linebreaks you put in the source code, you won't see anything from it back in the presentation (of course assuming you aren't using <pre> or white-space:pre). HTML uses the <br> element to represent a linebreak. So you basically indeed need to convert the real and invisible linebreaks denoted by the characters xA (newline, linefeed, LF, \n) and/or xD (carriage return, CR, \r) by a HTML <br> element.
In most programming languages you can just do this by a string replace of "\n" by "<br>".
You can wrap it in <pre> .. </pre>.
I have some leagacy reporting data which is accessed from SSRS via an xml web service data source. The service returns one big field containing formatted plain text.
I've been able to preserve white space in the output by replacing space chars with a non-breaking space, however, when exporting to PDF leading white space is not preserved on lines that do not begin with a visible character. So a report that should render like this:
Report Title
Name Sales
Bob 100.00
Wendy 199.50
Is rendered like this:
Report Title (leading white space stripped on this line)
Name Sales (intra-line white space is preserved)
Bob 100.00
Wendy 199.50
I've not been able to find any solution other than prefixing each line with a character which I really don't want to do.
Using SQL 2005 SP3
I googled and googled the answer to this question. Many answers included changing spaces to Chr(20) or Chr(160). I found a simple solution that seems to work.
If your leading spaces come from a tab stop replace "/t" with actual spaces, 5 or so
string newString = oldString.Replace("/t"," ")
In the expression field for the textbox I found that simply adding a null "Chr(0)" at the beginning of the string preserves the leading spaces.
Example:
=Chr(0) & "My Text"
Have you tried non-breaking spaces of the ASCII variety?
=Replace(Fields!Report.Value, " ", chr(160))
I use chr(160) to keep phone numbers together (12 345 6789). In your case you may want to only replace leading spaces.
You can use padding property of the textbox containing the text. Padding on the left can be increased to add space that does not get stripped on output.
I have used this work around:
In the Textbox properties select the alignment tab.
In the Padding option section edit the right or left padding(wherever you need to add space).
If you need to conditionally indent the text you can use the expression as well.
