[xsl] Finding the current node type

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
