RE: Re: Search and Replace Help
When you say that you are relying on the XSLT processors supplied as part of the web browser, then you will either have to: 1) Write a least-common-denominator stylesheet. That is to say one that relies only on features common to all processors. That is most likely an XSLT 1.0 processor with no extension functions. 2) Write a different stylesheet for each browser, using the features available for each browser's XSLT engine. XSLT 1.0's string handling features are fairly basic. That's why I suggested XSLT 2.0 and the regex functions. One could, of course pound the strings to death with the primitive XSLT 1.0 string handling functions in order to get what you need. After all, you could pull your own bad tooth yourself with a pair of pliers, but I wouldn't. -- Charles Knell cknell@xxxxxxxxxx - email -----Original Message----- From: Matthew Ebbertt <mje004@xxxxxxxx> Sent: Sun, 20 May 2007 10:27:11 -0400 To: <xsl-list@xxxxxxxxxxxxxxxxxxxxxx> Subject: Re: Search and Replace Help First off, thanks for the reply, I learned quite a bit. And now, because of that, I can refine my question a bit. The XML is output from vBulletin as is when someone downloads their Private Messages, I can't change that. My intention is to create an XSLT to format the output so that it is easier for users to read instead of them just looking at the raw XML. Because of that, my intent is for this to be viewed in a normal web browsers (I am using FF 2.0 for this). 1) Thanks for explaining the <![CDATA] tag to me, that explains why I see the <br /> tag instead of it doing what I expected it to. Is there some way to get the same effect as an XHTML/HTML <br /> within a <![CDATA] element? The search replace template that I found is replacing any linefeeds it finds with the <br />, but even with just the linefeeds it doesn't actually do a linefeed. 2) I'll keep looking around for a way to replace [QUOTE=name] [/QUOTE] with the correct XHTML/HTML, but unless I find a way around the <![CDATA] limitation, it won't matter. Thanks for the help so far, this is fun.
