General XSLT query

sdagger · June 23rd, 2009, 08:19 AM

OK here are some inputs and outputs expected. I hope this will help?

INPUTS
This will be from the sitemap xml but assume the input for one level will be:

Code:

<sitemap>
      <navlink>
             <description>some link one</description>       
              <linktarget>http//www.linkone.com</linktarget>       
       </navlink>
      <navlink>
             <description>some link two</description>       
              <linktarget>http//www.linkone.com</linktarget>       
       </navlink>
      <navlink>
             <description>some link three</description>       
              <linktarget>http//www.linkone.com</linktarget>       
       </navlink>
</sitemap>

OUTPUT
The output will simply just show the <description> as a hyperlink to <linktarget>.

I would like to loop through the sitemap xml and check the current page is the same as (x) in the sitemap loop. If it is the same, check to see if (x) is not the last link. If it is not, then display the next description and linktarget as the hyperlink. If it is the last link, simply do nothing or just output some generic text such as "last".

Does this help?

Trying to explain best I can.

XSLT does not have a concept of a page or current page, it processes XML input and transforms it to HTML or XML or plain text output.
If the environment you use XSLT with does have a concept of a current page then define a global parameter in your XSLT stylesheet that you can then set before the transformation to pass in the current page.
Then in your stylesheet you can check

Code:

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="1.0">

  <xsl:param name="cp"/>
  <xsl:variable name="np" select="/sitemap/navlink[linktarget = $cp]/following-sibling::navlink[1]"/>

  <xsl:template match="/">
       <xsl:choose>
            <xsl:when test="$np">
                 <a href="{$np/linktarget}">
                       <xsl:value-of select="$np/description"/>
                 </a>
             </xsl:when>
             <xsl:otherwise>last</xsl:otherwise>
       </xsl:choose>
</xsl:template>

</xsl:stylesheet>

Blimey, that was a speedy reply. I will certainly give that a try and let you know if that works.

Regarding your concept of the a currentpage, the environment I use must have this as this is what it uses to get the current page value:

Code:

<xsl:variable name="currPage">
   <xsl:value-of select="/Properties/Data/Result/page_info/@pagename" />
</xsl:variable>

This code is quite alien to me. I hope I can put your code example to good use.

Thank you again for taking the time to provide help. You truly are an expert.

Hi

Many thanks for your help but I am still struggling (just a little) with the code you supplied. I have learnt a lot from this so far.

Would it be possible to help me a little more as I have now got the true inputs used and its the link value property i'm struggling with (syntax). Here is the input to use:

Code:

<segment>
 <node id="fr7xrxbb" allow-children="true" visible-in-sitemap="true">
  <label key="">click here</label>
  <description />
    <link type="page" target="">
     <value>about_us/media_centre/index</value>
     <query-string preserve-qs-data="false" />
    </link>
  <aliases />
 </node>
</segment>

Almost there now and thank you again.

What is it exactly that you want to do with that input?
Assuming you want to check the value child element of your link element against the parameter you have then you simply need to adapt the XPaths:

Code:

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="1.0">

  <xsl:param name="cp"/>
  <xsl:variable name="np" select="/segment/node[link/value = $cp]/following-sibling::node[1]"/>

  <xsl:template match="/">
       <xsl:choose>
            <xsl:when test="$np">
                 <a href="{$np/link/value}">
                       <xsl:value-of select="$np/description"/>
                 </a>
             </xsl:when>
             <xsl:otherwise>last</xsl:otherwise>
       </xsl:choose>
</xsl:template>

</xsl:stylesheet>

I'm confused why you don't have access to the "real" XML, is it encrypted? Or do you lack sufficient rights to its location?

As Michael said, XSLT is just about transforming one file into another. If you don't have access to the code, there's no way you can do this job. Have the administrator who whoever has access to the information post for assistance. It sounds like there's some fundamental confusion about how XSLT works. Whoever has access to the XML is the person who HAS to write the XSLT.
