XSL error

Hi Experts,

I am stuck into few lines of codes of xslt.

when I am using below line of code without any condtion then I am getting required reult with no error:

<xsl:variable name="productDataXml"><xsl:value-of select="document('/../productsData_staticTemplate.xml')" /></xsl:variable>

But when I am using same line under some condition its throwing an error.

<xsl:if test="$previewValue = 'true'">
	<xsl:variable name="productDataXml"><xsl:value-of select="document('/../productsData_staticTemplate.xml')" /></xsl:variable>
</xsl:if>

I am getting below error:

javax.xml.transform.TransformerConfigurationException: Failed to compile stylesheet. 60 errors detected.

I searched for the possible soultion in every XSL forum and thought of posting here as well. I will appreciate any pointer on this.

Thanks in Advance!

The error's probably being triggered elsewhere in your XSL when you try to use $productDataXml, because it may or may not exist.

Swap the code around so you always defined $productDataXml and are just conditional about it's value, adding a conditional to check that value if necessary where you're using $productDataXml:

<xsl:variable name="productDataXml">
    <xsl:if test="$previewValue = 'true'">
        <xsl:value-of select="document('/../productsData_staticTemplate.xml')" />
    </xsl:if>
</xsl:variable>
.
.
.
<xsl:value-of select="$productDataXml"/>
or
<xsl:if test="not($productDataXml = '')">
    <xsl:value-of select="$productDataXml"/>
</xsl:if>

Thanks!

I will check the values of productDataXml.

Meanwhile I just want to let you know that I am facing this issue only when I am using any condition. Without any condition $productDataXml prints fine without any error.

Yep, it's not a question of what condition you wrap it in, it's the fact that you wrap the XSL variable declaration in a condition rather than it's value.

At the moment if $previewValue isn't the string "true" the variable $productDataXml doesn't get defined so where-ever in your code you use the value of $productDataXml you get the equivalent of a Java null pointer exception.

I have modified my code as u suggested and now true part is working fine:

<xsl:variable name="productDataXml">
	<xsl:choose>
		<xsl:when test="$isTeamsitePreview = 'true'">
			<xsl:value-of select="document('/../productsData_staticTemplate.xml')"/>							
		</xsl:when>
		<xsl: otherwise>			
			<xsl:value-of select="irwxsl-helper:getProductsInfoXmlNode(ac:adcopy/textlist/@id,$commandContext,$outputProprtyMap)"/> 				
		</xsl: otherwise>
	</xsl:choose>
</xsl:variable>

But now else part is showing problem. If I use else part then below piece of code is not working.

<xsl:variable name="new" select="$productDataXml/ir:name-rest/products/product/items/item[partNumber=$imageLink][1]/new"/>
<xsl:variable name="tro" select="$productDataXml/ir:name-rest/products/product/items/item[partNumber = $imageLink][1]/prices/normal/priceNormal/@tro"/&gt;
<xsl:variable name="nlp" select="$productDataXml/ir:name-rest/products/product/items/item[partNumber = $imageLink][1]/prices/normal/priceNormal/@nlp"/&gt;
<xsl:variable name="bti" select="$productDataXml/ir:name-rest/products/product/items/item[partNumber=$imageLink][1]/bti"/>
<xsl:variable name="family" select="$productDataXml/ir:name-rest/products/product/items/item[partNumber = $imageLink][1]/prices/family-normal/priceNormal"/>

but as soon as I removed the whole code and use only below line then I am getting the output without any issue.

<xsl:variable name="productDataXml" select="irwxsl-helper:getProductsInfoXmlNode(ac:adcopy/textlist/@id,$commandContext,$outputProprtyMap)" />

As I am new to XSL so could not able to debug the code. Please share the knowledge if you find something wrong in my code.

Thanks in advance!

It's hard to debug without seeing the whole code as there seems to be quite a lot going on.

The best tip I can give you is you use

<textarea>
    <xsl:copy-of select="."/>
</textarea>

blocks to dump out the XML that's actually being passed (as opposed to what you think/expect is being passed). The above would dump the current node but you can change "." to "/" to dump the root node, or "$variableName" to dump a variable.

You'll probably find that the value of $productDataXml in the else scenario isn't quite what you're expecting and is missing one of the nodes you're selectors are trying to match on in your other variable setters.
