RE: [xsl] Finding the current node type

Could you maybe give me an exact piece of code according to the XML file
Mark included in his original email?

Thanks!


(Sorry to sound like such a beginner (but hey, that's what I am!)...)

If I understand what you are trying to do, you could use local-name(). 
This will give you the name of the node.

Hi All

I'm trying to figure out a way to determine the "type" of the current
node in an nodeset.

I have a union of two dissimilar nodesets and I need to number the
combined set sequentially in my output. I also need to output details
from each node, but as they are completely different I need to process
each node type differently based on it's contents.

Here's a silly example

<products>
      <speaker>
              <woofer>12 inch</woofer>
              <rms_power>70 watts</rms_power>
              <peak_power>95 watts</peak_power>
              <height>40 inches</height>
              <width>18 inches</width>
              <depth>18 inches</depth>
      </speaker>
      <laptop>
              <disk>80GB</disk>
              <screen>15 inch</screen>
              <cpu>Intel Core Duo 2.3ghz</cpu>
              <weight>5.2lbs</weight>
      </laptop>
      ...
</products>

So, I need to do something like:

<xsl:for-each select="speaker | laptop">
      <!-- Assign a sequential Number -->
      Item No: <xsl:value-of select="position()"/> <br />
      <!-- Now output item-specific details -->
      <xsl:choose>
              <xsl:when test="node = speaker">
                      RMS Power: <xsl:value-of select="rms_power"/>
<br />
                      Peak Power: <xsl:value-of select="peak_power"/>
<br />        
              </xsl:when>
              <xsl:when test="node = laptop">
                      Disk Drive: <xsl:value-of select="disk"/> <br />
                      CPU: <xsl:value-of select="cpu"/> <br />

              </xsl:when>     
      </xsl:choose>
</xsl:for-each> 

So, what I need to figure out is the test in the when clause to see
which type of node I'm processing.

I could hack it with something like:
      
<xsl:when test="count(rms_power) &gt; 0"> 
      <!-- Must be a speaker -->
      RMS Power: <xsl:value-of select="rms_power"/>
      Peak Power: <xsl:value-of select="peak_power"/>         
</xsl:when>

However, it's messy and I have to find unique child nodes for every
product.

I'm sure there's a more elegant way

Can anyone help?

TIA

Mark
