Your example XML file does not contain elements with the local names "company" and "product". Your XSLT file is looking for them. Naturally it won't find them, so the transformation will fail.

This: <xsl:when test="//info">
and this: <xsl:if test="//info/company=$company and //info/product=$product">

are telling your stylesheet to start looking at the root for elements matching the test criteria.

Is that what you want? Or, do you want to look for "info" elements that are descendants of the "l1" element?

Since the latter makes sense to me and the former does not, maybe the XPath expression you are looking for is 

<xsl:when test=".//info">
and <xsl:if test=".//info/company=$company and .//info/product=$product">


N.B., there is a period character before the double-slash. That tells your stylesheet to start at the context node (<l1>, in this case) and not at the document root.

Get the element names correct and try these XPath expressions, and get back to us if you are still having a problem.

Subject:  [xsl] Problem with Xpath

Hi all:

I am having issues with Xpath. 

My xml looks like this:

<root>

<l1>
			<text>
				<para>First level</para>
			</text>
			<info>
				<comp>Kmart</comp>
				<prod>Shoes</prod>
			</info>
			<l2>
			<text>
				<para>Second level .</para>
			</text>
			</l2>
		</l1>
		<l1>
			<text>
				<para>Second level</para>
				<info>
				<comp>Kmart</comp>
				<prod>Shoes</prod>
			</info>
			</text>
		</l1>
			<l1>
			<text>
				<para>Third level</para>
				<info>
				<comp>Target</comp>
				<prod>Pen</prod>
			</info>
			</text>
		</l1>
</root>

Now, I have logic in my style sheet which says that
only if element <l1> contains element <info>, then
if <comp> and <prod> values match the values being
passed to the style sheet through two other parameters
<company> and <product> , then display l1 , otherwise
do not display l1.

The XSLT is :


<xsl:template match="l1">
<xsl:choose>
			<xsl:when test="//info">
				<xsl:if test="//info/company=$company and
//info/product=$product">
					<fo:list-block>
						<fo:list-item>
							<fo:list-item-label>
								<fo:block>
									<xsl:number format="1"/>
								</fo:block>
							</fo:list-item-label>
							<fo:list-item-body>
								<fo:block>
									<xsl:apply-templates/>
								</fo:block>
							</fo:list-item-body>
						</fo:list-item>
					</fo:list-block>
				</xsl:if>
			</xsl:when>
			<xsl:otherwise>
			<!-- Do something else-->
			</xsl:otherwise>
		</xsl:choose>
	</xsl:template>

So, if I have passed $company="KMart" and
$product="Shoes" on the style sheet, then the expected
output is:

1 First
2 Second

Instead, it matches only the company and product for
the first level and stops there. Can you please tell
me what is wrong with the xpath to company and product
on the style sheet?

Thank you in advance for your help.
