Subject: Re: [xsl] Finding the current node type|

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 />
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) > 0"> <!-- Must be a speaker -->
RMS Power: <xsl:value-of select="rms_power"/>
Peak Power: <xsl:value-of select="peak_power"/>
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?
