In case you know all possible types in advance, a simple (but not
too-efficient) way of picking up all "existing" gui types is the
following:
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
<xsl:output method="text"/>
<xsl:param name="pAllStyles" as="xs:string+"
select="'alertBox', 'combo', 'help', 'tooltip'"/>
<xsl:variable name="vDoc" select="/"/>
<xsl:template match="/">
<xsl:value-of separator="
" select=
"$pAllStyles[. = $vDoc/styles/gui/@type ]" />
</xsl:template>
</xsl:stylesheet>
When this transformation is applied on your source xml (provided with
a single element parent):
<styles>
<gui type="alertBox"/>
<gui type="tooltip"/>
<gui type="help"/>
<gui type="tooltip"/>
<gui type="alertBox"/>
<gui type="tooltip"/>
<gui type="help"/>
</styles>
the wanted result is produced:
alertBox
help
tooltip

Dimitre.

I'm having great difficulty understanding how/if XSL provides the tool to
satisfy the following simple requirement.
Lets say I have some simple xml like :
<gui type="alertBox">...</gui>
<gui type="tooltip">...</gui>
<gui type="help">...</gui>
<gui type="tooltip">...</gui>
<gui type="alertBox">...</gui>
<gui type="tooltip">...</gui>
<gui type="help">...</gui>
To simplify things... imagine transforming this document in such a way that
we have something like :
<alertBox/>
<tooltip/>
<help/>
i.e. I would like the XSL to result in one output per gui type.
So there is the problem... how on earth do I process the xml such that it
results in an output per +type+ rather than for each instance (is that
explained well enough?)... i.e. it's easy to match on the attributes but each
match produces output so I would get :
<alertBox/><alertBox/>
<tooltip/><tooltip/><tooltip/>
<help/><help/>
Can anyone offer advice on the way in which I ought to approach this problem?
Kindest regards,
Ben
