Facing issues in parsing xml with xslt - html

Question

I am trying to parse a xml to generate a html report.The problematic section of the xml is as given
<failure message="Management changes link count is not 3$HiHello" type="junit.framework.AssertionFailedError">junit.framework.AssertionFailedError: Management changes link count is not 3$HiHelloJI
at CustomProjects.CommonTemplates.verifyManagementChanges(Unknown Source)
at CustomProjects.EmersonTest.testEmerson_VerifyManagementChanges(Unknown Source)
</failure>
The xslt written for parsing this is :
<xsl:choose>
<xsl:when test="failure">
<td>Failure</td>
<td><xsl:apply-templates select="failure"/></td>
<td>screenshot</td>
<td><xsl:apply-templates select="failurelink"/></td>
</xsl:when>
</xsl:choose>
<xsl:template match="failure">
<xsl:call-template name="display-failures"/>
</xsl:template>
<xsl:template match="failurelink">
<xsl:call-template name="display-failures-link"/>
</xsl:template>
<xsl:template name="display-failures">
<xsl:param name="FailText" select="#message"/>
<xsl:choose>
<xsl:when test="not(#message)">N/A</xsl:when>
<xsl:otherwise>
<xsl:value-of select="substring-before($FailText,'$')"/>
</xsl:otherwise>
</xsl:choose>
<!-- display the stacktrace -->
<code>
<br/><br/>
<xsl:call-template name="br-replace">
<xsl:with-param name="word" select="."/>
</xsl:call-template>
</code>
<!-- the later is better but might be problematic for non-21" monitors... -->
<!--pre><xsl:value-of select="."/></pre-->
</xsl:template>
<xsl:template name="display-failures-link">
<xsl:param name="linktext" select="#message"/>
<xsl:choose>
<xsl:when test="not(#message)">N/A</xsl:when>
<xsl:otherwise>
<xsl:value-of select="substring-after($linktext,'$')"/>
</xsl:otherwise>
</xsl:choose>
<!-- display the stacktrace -->
<code>
<br/><br/>
<xsl:call-template name="br-replace">
<xsl:with-param name="word" select="."/>
</xsl:call-template>
</code>
<!-- the later is better but might be problematic for non-21" monitors... -->
<!--pre><xsl:value-of select="."/></pre-->
</xsl:template>
Here I am getting the desired result(The String before $ sign) from display-failures template but on calling display-failures-link I am getting nothing.(Should get the string after $ sign).I dont know whether the problem is with sunstring function or with something else.Kindly let me know what I am doing wrong here.
Any help is highly appreciated.

The problem here is that you are trying to apply-templates on the XPath failurelink, but you don't have an element called <failurelink>, so this apply-templates isn't finding anything.
<xsl:apply-templates select="failurelink"/>
One way to apply two different templates on the same kind of element is to use modes:
<xsl:template match="failure">
<xsl:call-template name="display-failures"/>
</xsl:template>
<xsl:template match="failure" mode="link">
<xsl:call-template name="display-failures-link"/>
</xsl:template>
Then the area where you apply the templates would change to this:
<td>Failure</td>
<td><xsl:apply-templates select="failure"/></td>
<td>screenshot</td>
<td><xsl:apply-templates select="failure" mode="link"/></td>
But in your case, there's an even better approach. Just eliminate the second template, and do this:
Replace the whole <xsl:choose> with:
<xsl:apply-templates select="failure" />
Replace the first template you listed with:
<xsl:template match="failure">
<td>Failure</td>
<td><xsl:call-template name="display-failures"/></td>
<td>screenshot</td>
<td><xsl:call-template name="display-failures-link"/></td>
</xsl:template>
And delete the second template you listed.
