Hi,
I can't find a way to solve this problem:
How do I extract the value of an element, without text in its children. E.g.
how do I extract from the next example the line 'This text is some test .'.
<text>This text is some test <emph>text</emph>.</text>
I think I am overlooking a simple function, but can't seem to find it.
The crucial thing to grasp here is that <text> contains the text node
"This text is some test ", the element <emph> and then another text
node "."
When you do value-of on <text> you get the text nodes of the element
and all its children concatenated together, so you would get the text
node child of <emph> - which isnt what you want.
When you do value-of select="text()" on <text> to only get the text
node children you get a sequence of two items - the two text nodes.
In 1.0 when you have a list of more than one item the first is used
and the rest discarded (to allow functions that expect a single item
to not fail if a list is supplied - XSLT 1.0 was designed to always
produce some output).
What all this means is that in 1.0 you can do either:
<xsl:for-each select="text()">
<xsl:value-of select="."/>
</xsl:for-each>
or
<xsl:apply-templates select="text()"/>
Either technique will process each text node in turn.
In 2.0 all the items in the sequence get concatenated together using a
separator (if one's not supplied the default of a single space is
used), so a simple value-of select="text()" does the job.
