Hyperlink in XSL

[yuppieyash]

hi,

I am converting an XML file to HTML file using XSLT. I have a table with 3 columns viz action, count, time. Once i fill the table with values, i need to sort it based on what i click. i.e. if i click on action, it should sort by action, if i click on count, it should sort by count. So how do i create hyperlink for the attributes action, count, time in XSLT and how do i monitor which attribute has been clicked so that i can sort by that attribute in XSLT? Any replies greatly appreciated.

Thanks,
anki

Welcome to WebmasterWorld, YY.

What is the structure of your XML?

Thanks for the reply. The structure goes like this:

<data>
<log_entry run_time="4086" action="retrieveUserPreferencesBean" username="PROJNAV" />
<log_entry run_time="571" action="retrieveCommentsBean" username="PROJNAV"/>
</data>

Thanks,
YY

Okay, let's slow down.

Assuming

1) the action is represented by the action attribute of <log_entry>
2) the time is the run_time attribute of <log_entry>
3) the count is the position of the <log_entry>

and

4) the parameter $sortkey will be defined as "time" for @run_time or "action" for @action, and ignored in other cases

then to display <data> as a table sorted on one of these three pieces of data, you'd use XSL similar to this code. How the value of $sortkey gets passed to the template depends on where the stylesheet is being called from and how your processing engine accepts parameters.

<xsl:template match="data"> 
 <!-- reserve $sortkey; if a global parameter this line is not necessary --> 
 <xsl:param name="sortkey" /> 
 <!-- set up the table to display the output --> 
 <table> 
 <tr> 
 <th>count</th> 
 <th>run_time</th> 
 <th>action</th> 
 </tr> 
 <!-- process on each /data/log_entry element --> 
 <xsl:choose> 
 <xsl:when test="$sortkey = 'action'"> 
 <xsl:apply-templates> 
  <xsl:sort select="@action" /> 
 </xsl:apply-templates> 
 </xsl:when> 
 <xsl:when test="$sortkey = 'time'"> 
 <xsl:apply-templates> 
  <xsl:sort select="@run_time" data-type="number" /> 
 </xsl:apply-templates> 
 </xsl:when> 
 <xsl:otherwise> <!-- default sortkey is count --> 
 <xsl:apply-templates /> 
 </xsl:otherwise> 
 </xsl:choose> 
 </table> 
</xsl:template> 
<xsl:template match="log_entry"> 
 <!-- display each log_entry in a table row --> 
 <tr> 
 <td><xsl:value-of select="position()" /></td> 
 <td><xsl:value-of select="@run_time" /></td> 
 <td><xsl:value-of select="@action" /></td> 
 </tr> 
</xsl:template>
