RE: How to search for <, >, etc. in a string?

Hello Mike,

That is exactly what was getting me.  I'm learning more and more gotchas everyday.  It keeps me on my toes and makes it fun!

Thanks,

Remember that CDATA and &lt; are all processed by the XML parser before the
XSLT processor gets a look in. So the string that the XSLT processor sees is

<u>Link containing a & character</u>

and the string that you want to look for is

<u>

So you need to write a string that the XSLT processor will see as <u>, and
you can do this by writing &lt;u&gt; in your source stylesheet.

The more likely source of your problem is the "starts-with" Your example
doesn't start with <u>, it starts with white space. The fact that the white
space is outside the CDATA section is irrelevant. Use normalize-space() to
remove the white space.
