xsl template question

[Angelo Bonaparte]

Hi, I'm trying to get familiar with XSL and got the following code from the web that replaces a string withing a string with a selected string. Ie. let's says I have [email protected] I would like to replace it with george_REMOVE_AT_mysite.com. So here is the template....

   <xsl:template name="replace-string">
    <xsl:param name="text"/>
    <xsl:param name="replace"/>
    <xsl:param name="with"/>
    <xsl:choose>
      <xsl:when test="contains($text,$replace)">
        <xsl:value-of select="substring-before($text,$replace)"/>
        <xsl:value-of select="$with"/>
        <xsl:call-template name="replace-string">
          <xsl:with-param name="text"
select="substring-after($text,$replace)"/>
          <xsl:with-param name="replace" select="$replace"/>
          <xsl:with-param name="with" select="$with"/>
        </xsl:call-template>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="$text"/>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template> 

and here is how i try to access it. I can't seem to find the correct way to call it. I get Could not find function: replace-string. The code works if I just display text but it crashes when I try to use the replace-string template.

  
 <xsl:template match="theEmail">
  <xsl:variable name="title" select="name()"/>
  <xsl:variable name="label" select="normalize-space($abcdDescText/translationTable/translation[@name=$title]/text[@lang=$lang])"/>
  <xsl:if test="string-length(text())>0">
    <dd>
      <span class="label"><xsl:value-of select="$label"/>:</span>
      
      <xsl:call-template name="replace-string"> 
          <xsl:with-param name="$text" select="replace-string(text, '@',                                 REMOVE_AT_"/>
       </xsl:call-template>
    </dd>
  </xsl:if>
</xsl:template> 

Thanks for any guidance.

You call it in your main template in exactly the same way you called it recursively in itself:

<xsl:call-template name="replace-string"> 
    <xsl:with-param name="text" select="$text"/>
    <xsl:with-param name="replace" select='@'/>
    <xsl:with-param name="with" select="REMOVE_AT_"/>
</xsl:call-template>

That did the trick. I just gotta figure out how to display the result of calling that template. I tried a few ways already but without success.

[Paul Clapham]

That depends on what you mean by "display". Normally an XSLT stylesheet produces a result (which can be XML or HTML or text). So by "display" do you mean you want the xsl:call-template element to include something in the result? It doesn't return a value itself, so whatever it is you want included in the result, the template has to do that.

But if you wrap that in an xsl:variable element, then that variable becomes the output destination for the time being.

Thanks for your response it's appreciated. Before I added a template to replace the @ to AT in an email address I had the following wich rendered the html to display Email Address: then the email address.

Here is the code:

  
<xsl:template match="email">
  <xsl:variable name="title" select="name()"/>
  <xsl:variable name="label" select="normalize-space($abcdText/translationTable/translation[@name=$title]/text[@lang=$lang])"/>
  <xsl:if test="string-length(text())>0">
    <dd>
      <span class="label"><xsl:value-of select="$label"/>:</span>
      <A><xsl:attribute name="href">mailto:<xsl:value-of select="text()"/></xsl:attribute>
      <xsl:value-of select="text()"/></A>
    </dd>
  </xsl:if>
</xsl:template>
 

Now with the code below my html renders, no errors occur but I only get the label, the actual email with the @ removed doesn't show. Here is the code.
Again, thanks for all your help.

  
 
<xsl:template match="cntemail">
  <xsl:variable name="title" select="name()"/>
  <xsl:variable name="label" select="normalize-space($abcdText/translationTable/translation[@name=$title]/text[@lang=$lang])"/>
  <xsl:if test="string-length(text())>0">
    <dd>
      <span class="label"><xsl:value-of select="$label"/>:</span>
      
      <xsl:call-template name="replace-string"> 
               <xsl:with-param name="text" select="text" />
               <xsl:with-param name="replace">@</xsl:with-param>
               <xsl:with-param name="with">_REMOVE_AT_@_</xsl:with-param>
       </xsl:call-template>
      
    </dd>
  </xsl:if>
</xsl:template>

You passed the constant string "text" to the template. Based on what you posted earlier, I would expect to see that same string appearing in the output. (I do that all the time too.)

[Angelo Bonaparte]

Thanks. I will try again but so far I only get the label Contact Email:
but the email address doesn't appear. I will try different things to see what happens.
