Hi David,
Well, assuming you can't switch processors as outlined by Kip in that very
on-topic post....
At 01:19 AM 11/8/2003, you wrote:
Technically I can probably put the
lookup table in the input source since I'm getting it back from a
Database Query. One other question, is there any way to use XPath to
eliminate duplicates from a Node Set.
Yes, but we need to understand what you mean by "duplicate".
Since my XML I'm dealing with
looks something like:
<DGS>
<BOOKMARKS>
<TABLE>
<BMTABLE>CMSCASE</BMTABLE>
</TABLE>
<TABLE>
<BMTABLE>CMSCASE</BMTABLE>
</TABLE>
<TABLE>
<BMTABLE>CMSCASE</BMTABLE>
</TABLE>
<TABLE>
<BMTABLE>CMSCASE</BMTABLE>
</TABLE>
<TABLE>
<BMTABLE>EMPREP</BMTABLE>
</TABLE>
<TABLE>
<BMTABLE>EMPREP</BMTABLE>
</TABLE>
</BOOKMARKS>
</DGS>
Is there anyway to get a TABLE nodeset that would just return the
following using XPATH:
<TABLE>
<BMTABLE>CMSCASE</BMTABLE>
<BMTABLE>EMPREP</BMTABLE>
</TABLE>
Yes, de-duplicating is possible; you most commonly see it as a step along
the way to grouping.
The most popular and friendly way, assuming you're familiar with keys, is
to declare a key that lets you retrieve nodes by their value, and then when
you process a node, test whether it's the first (or last) of the nodes
retrieved by the key with the current value. This can be done either with
the generate-id() function or by using a counting-the-union approach for
testing node identity.
That's the explanation in prose; more useful to you would be to see the
code, which you can find in any resource like the XSL FAQ,
www.jennitennison.com, or any on- or off-line resource that describes
grouping in XSLT 1.0.
Cheers,
Wendell
I'll keep looking for an interface to a processor that supports the
document() function as that is the easiest way I can see in getting
this to work (the site this will be implemented on is using XALAN so I
don't have to worry about it when its in production).
