Prefix line number and keep line format?

[jtp51]

I'd like to prefix each line with it's line number and retain the line format.

This is not for source code.

For example, I have the following XML:

<filter-mapping>
     <filter-name>extensionsFilter</filter-name>
     <url-pattern>/faces/*</url-pattern>
</filter-mapping>

What I would like to format as and output:

1 <filter-mapping>
2      <filter-name>extensionsFilter</filter-name>
3      <url-pattern>/faces/*</url-pattern>
4 </filter-mapping>

Looking at the String functions, I am unsure about how to go about this. Prefix the line number should be no problem, but what about retaining the format?

Thanks,

Use the <pre>...</pre> tags in the HTML output to maintain the white-space and line breaks.

PS: Also remember that you'll probably need to use the htmlspecialchars() function so that the browser does not interpret the "<" characters as starting HTML tags.
