[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Splitting text nodes - xsl:iterate?
 Hi list,
Given an input document looking something like this:
<doc>
<head><foo/><bar/><baz/></head>
<body>
<sec>
<para>Lorem ipsum dolor sit amet, consectetur adipiscing elit.<box
outline="maybe"><para quack="y">Proin id <?foo bar?>bibendum urna, <baz>ut
ornare</baz> mi.</para></box></para>
<para>Aenean dui risus, <qux>sodales quis leo sit amet, ornare
consequat</qux> metus. Ut vel massa congue, egestas nibh et, rutrum
odio.</para>
</sec>
</body>
</doc>
(i.e. document markup consisting of arbitrary text and element nodes
nested to some unknown depth)
and the requirement for two separate outputs looking like these:
<doc>
<head><foo/><bar/><baz/></head>
<body>
<sec>
<para><new:start/>Lorem ipsum dolor sit amet, consectetur adipiscing
elit.<box outline="maybe"><para quack="y">Proin id <?foo bar?>bibendum
urna, <baz>ut ornare</baz> mi.</para></box></para>
<para>Aenean dui risus, <qux>sodales quis <new:end/>leo sit amet,
ornare consequat</qux> metus. Ut vel massa congue, egestas nibh et, rutrum
odio.</para>
</sec>
</body>
</doc>
<sec>
<para>Lorem ipsum dolor sit amet, consectetur adipiscing elit.<box
outline="maybe"><para quack="y">Proin id <?foo bar?>bibendum urna, <baz>ut
ornare</baz> mi.</para></box></para>
<para>Aenean dui risus, <qux>sodales quis [...]</qux></para>
</sec>
(i.e. a copy of the input, with new:start and new:end elements marking the
first 20 words of the document; and separately a copy of those first
twenty words, preserving all markup within them and adding ellipses at the
end)
...how might I fruitfully approach the transformation in an XSLT idiom? I
feel that there should be some neat declarative way of doing it, possibly
using xsl:iterate and/or accumulators, that I'm just failing to see. XSLT
3.0 is available (Saxon 9.6), but the source documents are old content and
not open to adjustment, sadly. I've tried using xsl:iterate, but I seem to
be falling down in keeping track of whether or not I'm processing the
specific text node in which the break needs to occur.
Am I making a rod for my own back here? Should I just be breaking out to a
custom Java function and crossing my fingers that I manage to avoid
ill-formed output? Any advice will be very gratefully received!
Thanks!
