Hi,
I'm writing a small xsl stylesheet to select a subset of
nodes from an xml
document. The important part looks like this...
<xsl:param name="PRODUCTGROUP" />
<xsl:param name="PLATFORM" />
<xsl:param name="ITEM" />
<xsl:for-each select="/store/productGroup[(_at_)type =
$PRODUCTGROUP]/platform[(_at_)type=$PLATFORM]/item[(_at_)type=$ITEM]">
etc..
What happens is I pass in the values of productgroup,
platform and item with
php. I can then retrieve a list of all items the attributes
of which match
the criteria. This seems to work fine, the only trouble is,
I'd like in
some cases to be able to choose all items, regardless of
attributes, like
so...
<xsl:for-each select="/store/productGroup/platform/item">
or any combination, like so...
<xsl:for-each
select="/store/productGroup/platform[(_at_)type=$PLATFORM]/item">
I guess I'm a bit unclear how to be able to choose between multiple
node-sets, depending on the whether or not one of the
parameters is set.
I've been searching for info on this most of the afternoon,
but can't seem
to find much.
If @type always has a non-zero-length value, then
<xsl:for-each select="/store/productGroup[(_at_)type=$PRODUCTGROUP or
$PRODUCTGROUP=""]/platform[(_at_)type=$PLATFORM or
$PLATFORM=""]/item[(_at_)type=$ITEM or $ITEM=""]">
would work.
