RE: [xsl] Help parsing a node

[Michele R Combs <mrrothen@xxxxxxx>]

OK, that fixed the error, thank you.

However, now when we get to <for-each select="$uniqueTypes">, nothing happens.
That is, where previously I would see each of these container types in my
output, I don't see anything.

Michele,

Martin wrote "xsl:key", but for whatever reason his fingers seem to have typed
"xsl:name". Try what he meant to say and it should work.

If you aren't familiar with keys and how powerful and useful they are, now is
a good moment to learn. One of their several uses is in getting around scaling
problems when grouping (or doing any handling of unique
values) in XSLT 1.0.

Also ... your diagnosis is not *quite* correct yet:

<xsl:variable name="uniqueTypes"
select="ead/archdesc/dsc/descendant::*/container[not(@type=following::
*/container/@type)]/@type" />

With the root node as context, this is selecting all container elements in
descendants of /ead/archdesc/dsc whose type is not the same as that of a
container *child* of a following element.

So, while following siblings are indeed found on the following:: axis, this in
fact is checking elements against nieces (and/or nephews) or cousins (at
various removes), but not against siblings.

Cheers,
Wendell
