Intersecting Nodeset

[Xeon]

Hi,

I got a XML data node like this :

<item firstkey="01" secondkey="02"/>

I setup 2 lookup tables by :

<xsl:key name="key1" match="item" use="@firstkey"/>
<xsl:key name="key2" match="item" use="@secondkey"/>

Now, I need to extract nodes with specific @firstkey & @seconkey. So
how do I do this intersecting nodes extraction? or do I have to
concede to using :

key('key1', $somekey)[@secondkey = $someotherkey]

Any help appreciated
TIA

Solution 1:
Define the following:

<xsl:key name="k1-2" match="item" use="concat(@firstkey, '|',
@secondkey)"/>

Then all "item" elements that have specific values for their "firstkey" and
"secondkey" attributes will be selected by:

key('k1-2', concat($somekey, '|', $someotherkey))


Solution2:

key('key1', $somekey)
[count(. | key('key2', $someotherkey))
=
count(key('key2', $someotherkey))
]
