copied!<p>Rather than using an <strong>xsl:for-each</strong> and then a call to a named template, you could consider combining the two into one <strong>xsl:apply-templates</strong> call. Firstly, you would select the comments with a ResponseCommentID attribute of 0.</p> <pre><code><xsl:apply-templates select="in:inputs/in:result[@name='XML_Comment']/root/Comments[@ResponseCommentID='0']" /> </code></pre> <p>Then, you would have a template to match the <strong>Comments</strong> attribute, where you would output the comment details. You could then recursively get the response comments like so:</p> <pre><code><xsl:apply-templates select="../Comments[@ResponseCommentID = current()/@CommentID]" /> </code></pre> <p>This would just recursively call the same <strong>Comments</strong> template until there are no more reponses.</p> <p>Here is the full XSLT in this case (I am outputting the comments as list items in HTML just as an example)</p> <pre><code><xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:in="http://www.composite.net/ns/transformation/input/1.0" exclude-result-prefixes="in"> <xsl:output method="xml" indent="yes"/> <xsl:template match="/"> <ul> <xsl:apply-templates select="in:inputs/in:result[@name='XML_Comment']/root/Comments[@ResponseCommentID='0']" /> </ul> </xsl:template> <xsl:template match="Comments"> <li> <xsl:value-of select="@Comment" /> <xsl:if test="../Comments[@ResponseCommentID = current()/@CommentID]"> <ul> <xsl:apply-templates select="../Comments[@ResponseCommentID = current()/@CommentID]" /> </ul> </xsl:if> </li> </xsl:template> </xsl:stylesheet> </code></pre> <p>This gives the following output</p> <pre><code><ul> <li>test comment!!!! <ul> <li>my response <ul> <li>I don't agree with Norman. Terrible response.</li> </ul> </li> <li>I've got something to say!</li> </ul> </li> <li>test comment2!!!!</li> <li>Not impressed... <ul> <li>I'm impressed.</li> </ul> </li> <li>blah blah blah. <ul> <li>this is a response to blah blah blah.</li> </ul> </li> <li>dfsfs</li> </ul> </code></pre> <p>However, it would be more efficient to use an <strong>xsl:key</strong> here to look up the responses to comments:</p> <pre><code><xsl:key name="Comments" match="Comments" use="@ResponseCommentID" /> </code></pre> <p>Then to get the top-level comments you would do this:</p> <pre><code><xsl:apply-templates select="key('Comments', '0')" /> </code></pre> <p>And to get the responses to a given comment in your matching template, you would do this</p> <pre><code><xsl:apply-templates select="key('Comments', @CommentID)" /> </code></pre> <p>The following XSLT also gives the same results</p> <pre><code><xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:in="http://www.composite.net/ns/transformation/input/1.0" exclude-result-prefixes="in"> <xsl:output method="xml" indent="yes"/> <xsl:key name="Comments" match="Comments" use="@ResponseCommentID" /> <xsl:template match="/"> <ul> <xsl:apply-templates select="key('Comments', '0')" /> </ul> </xsl:template> <xsl:template match="Comments"> <li> <xsl:value-of select="@Comment" /> <xsl:if test="key('Comments', @CommentID)"> <ul> <xsl:apply-templates select="key('Comments', @CommentID)" /> </ul> </xsl:if> </li> </xsl:template> </xsl:stylesheet> </code></pre>
