How can I include an if statement in my loop conditional in XSLT?
I have 2 or 3 different scenarios that define the data I want to loop through. For example, there may or may not be a product ID. If there is, I want to only loop through records that contain that product ID, otherwise I want all records. I was trying to do something like this:
<xsl:variable name="knowledgebaseLoop">
<xsl:choose>
<xsl:when test="string-length($productId) > 0">
<xsl:copy-of select="$currentPage/child::* [@parentID = $parentId]"/>
</xsl:when>
<xsl:otherwise>
<xsl:copy-of select="$currentPage/child::* [@parentID = $parentId]"/>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<xsl:for-each select="knowledgebaseLoop">
<xsl:if test="position() > $recordsPerPage * number($pageNumber - 1) and position() <= number($recordsPerPage * number($pageNumber - 1) + $recordsPerPage )">
<div id="main_body_listing">
<div class="listing_title2"><a href="{umbraco.library:NiceUrl(current()/@id)}"><xsl:value-of select="current()/@nodeName"/></a></div>
<xsl:value-of select="current()/summary"/>
</div>
</xsl:if>
</xsl:for-each>
But it’s unable to parse the XSLT. I know the 2 conditions are the same, I was going to rewrite one once I got it working. Thanks in advance for any help!
UPDATE:
Here is some sample XML:
<Knowledgebase id="1073" parentID="-1" level="1" writerID="0" creatorID="0" nodeType="1062" template="1083" sortOrder="5" createDate="2011-04-20T13:43:41" updateDate="2011-05-11T14:34:23" nodeName="Knowledgebase" urlName="knowledgebase" writerName="Chris" creatorName="Chris" path="-1,1073" isDoc=""><pageTitle>Knowledgebase</pageTitle><metaDescription>knowledgebase</metaDescription><metaKeywords>knowledgebase</metaKeywords><umbracoUrlName /><Article id="1074" parentID="1073" level="2" writerID="0" creatorID="0" nodeType="1063" template="1084" sortOrder="1" createDate="2011-04-20T13:44:13" updateDate="2011-05-16T09:39:12" nodeName="What is the answer to this question?" urlName="what-is-the-answer-to-this-question" writerName="Chris" creatorName="Chris" path="-1,1073,1074" isDoc=""><title>Change 2 Test 2</title><summary>Change 2 Test 2</summary><description>

I always need the articles where the parent ID is 1073. If and only if a product ID exists, I want the articles where the product ID is in the relatedProducts list. Thanks again!
Use:
Here is a complete and short example:
when this transformation is applied on the following XML document (based on the provided one in the Update, but made more interesting):
the wanted, correct result is produced (only Articles with
parentID="1073"or whoserelatedProductscontains the$pProductId(1077)):
