Parsing content with XSLT to replace custom tag

Hi folks,

Here is what I am trying to do:


I have a block of text within a database that I am feeding out to a page.  Within that text block, I have a "custom tag" ----

<workshop />


What I'd like to do is parse that block of content through an XSLT (i've got this part working already) and replace that <workshop /> tag with some other text.

I current have it printing out the other text, but it's not coming through at the same place in the code where the custom tag was - it's either writing above or below the content block depending on my .xsl file.  I will post my XSL file below, and any help is appreciated.

Please don't be surprised if my current file is not the correct way to do things - i'd be very surprised if it was correct at all.


THanks for your assistance,


bruno

Here is my XSLT file as it currently stands:






<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<!-- Ektron revision date: 2002-11-12 -->

<xsl:output method="html"/>

      <xsl:template match="/">
            
            <xsl:copy-of select="node()"/>
            
            <xsl:apply-templates select="//workshop"/>
            <xsl:apply-templates select="body/node()"/>
      </xsl:template>
      
      
      
      <xsl:template match="workshop">
            <b>Hello World</b>
      </xsl:template>
      
            
      <xsl:template match="@*|node()">
            <xsl:copy>
                  <xsl:apply-templates select="@*|node()"/>
            </xsl:copy>
      </xsl:template>      
      
      
      
</xsl:stylesheet>

hm....why not to use RegularExpression for this?

if you only need to find some text (<workshop />) and replace it with another RegularExpression will be much faster, clear and easier.

XSLT is for transforming, but if you don't want to transform anything, it's only waste of resources.

Ok, so I tried this, and it broke:






<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">


<xsl:output method="html"/>

     <xsl:template match="/">
          <xsl:apply-templates />
     </xsl:template>
     
     <xsl:template match="@*|node()">
          <xsl:copy>
               <xsl:apply-templates select="@*|node()"/>
          </xsl:copy>
     </xsl:template>    
     
     <xsl:template match="workshop">
          <% ecmCollection 6,"ecmNavigation" %>
     </xsl:template>    
</xsl:stylesheet>

Ok, that is now writing out my ASP to the page, but not executing it...not much better than if I just put the asp code into the database itself.

am i going about this the wrong way?  do you understand what I am trying to do?

It's normal. XML can be reused in different solutions rather than ASP.

About execution: it's harder:
- You can create temporary asp page (with temporary name) and call Server.Execute  (will be a pain to pass variables).
- Split result of XSLT on strings and code using as delimiters "<%" and "%>" and then output strings and execute code using VBScript's Execute statement
- Also look at http://www.experts-exchange.com/Web/Web_Languages/XML/Q_20960349.html

Got it working, didn't realize i could just make my xslt into an asp page and do it that way...

points go to Yury for getting the content into the right place.

here is my file now:







<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">


<xsl:output method="html"/>

     <xsl:template match="/">
          <xsl:apply-templates />
     </xsl:template>
     
     <xsl:template match="@*|node()">
          <xsl:copy>
               <xsl:apply-templates select="@*|node()"/>
          </xsl:copy>
     </xsl:template>    
     
     <xsl:template match="workshop">
          <% ecmCustomCollection 14,"ecmWorkshops" %>
     </xsl:template>    
</xsl:stylesheet>
