Node count and occurence - XSL

Question

I need to write generic xsl that would take in an xml document and output the count of nodes and their names. So if I have a file like the following:

   <assets>
    <asset>
        <type>hardware</type>
        <item>
            <name>HP laptop</name>
            <value>799</value>
        </item>
        <item>
            <name>server</name>
            <value>1000</value>
        </item>
        <item>
            <name>ViewSonic Monitor</name>
            <value>399</value>
        </item>
    </asset>
    <asset>
        <type>software</type>
        <item>
            <name>Windows Vista</name>
            <value>399</value>
        </item>
        <item>
            <name>Office XP</name>
            <value>499</value>
        </item>
        <item>
            <name>Windows 7</name>
            <value>399</value>
        </item>
          <item>
            <name>MS Project Professional 2007</name>
            <value>299</value>
          </item>
       </asset>
    </assets>

The output would be:

   <output>
    <node name="assets" count="1"/>
    <node name="asset" count="2"/>
    <node name= "type" count="??"/>
    <node name="item" count=??/>
    <node name="name" count=??/>
    <node name="value" count=??/>
    </output>

Answer 1

You'll want to use the count function:

<xsl:value-of select="count(assets/asset)" />

So your code would look like:

Assets: <xsl:value-of select="count(assets)" />
Asset:  <xsl:value-of select="count(assets/asset)" />
Item:   <xsl:value-of select="count(assets/asset/item)" />
