Hey guys trying to figure this out. wondering if anyone could help.

  <make desc="Assembled Vehicle" value="ASVE">
      <assembled />
  </make>


I need to match on if assembled element is there. When I find it I will output the make desc and value.

Here is what I come up with so far:

 <xsl:if test="@node::child() = 'aircraft'">
      I know you can't do this, but just wondering if I am on the right track?

Thanks again.

sorry i meant....

<xsl:if test="@node::child() = 'assembled'">

<xsl:template match="make">
 <xsl:if test="assembled">
  <xsl:value-of select="@desc"/>
 </xsl:if>
</xsl:template>

Michael, sorry to bother you again but I am having a tough time figuring this out. I have the following and trying to check make and if it has a value of aircraft in addition if aircraft has children of code.

<make desc="Chrysler" value="CHRY">
        <aircraft/>
 </make>
 <make desc="test">
        <aircraft>
                 <code desc="Jet Propelled" value="JET"/>
         </aircraft>
  </make>


This is what I have:
 <xsl:if test="child::node() = aircraft and ??>

it is after the and that I am struggling here is where I need to see if aircraft has any 'code' children, I just have to know if they are present.

Here is what I was guessing but i guess you can't do it:
child::node(aircraft)

P.S. Michael I have purchased your book off of amazon.com

Thanks again sorry to be a bother.

As I said before, you want

<xsl:if test="aircraft">

That's short for

<xsl:if test="boolean(child::aircraft)">

that is, it selects the children called "aicraft" to produce a node-set, and converts this node-set to a boolean; the result is true if the node-set is not empty.

Your code test="child::node() = aircraft" doesn't work because "=" tests the value of the node (that is its content) rather than its name: more strictly, the string-value of the node, which in the case of an element is the concatenation of all the text nodes within it, which in your case is a chunk of whitespace.

Hello again, I am trying a new solution: below is the code that my xml that my style sheet parses(sorry if it is long) and my style sheet code is below that...I am trying to sort on @value. I have also included my output at the end. Thanks again...sorry, but i am still a newbie at all of this:

Let's look at your code and see what it means.

<xsl:template match="@*|node()">

This is processing any element or attribute (or text node, etc) that you apply-templates to. You never apply templates to an attribute node, so why have a template rule that matches one?

    <xsl:apply-templates />

If you're processing an element, this causes all the children to be processed.

    <xsl:for-each select="aircraft">

If you're processing an element with aircraft children, this causes the aircraft children to be processed a second time.

     <xsl:sort select="../@value" />

You want the aircraft children to be sorted. But in your data, there is never more than one aircraft child, so sorting them has no effect. And even if there was more than one aircraft, the expression ../@value would return the same result for each one, so the sort would be meaningless.
