Summary
Returns an xml fragment between two milestone elements. The result sequence is wrapped into a parent element node.
Required input
XSLT parameters:
* ms1Name (first milestone name): "pb" * ms1Position (first milestone position): 1 * ms2Name (second milestone name): "pb" * ms2Position (second milestone position): 2
XML document:
<?xml version="1.0" encoding="utf-8"?>
<TEI xmlns="http://www.tei-c.org/ns/1.0">
<text>
<body>
<pb n="1"/>
<p>
<s>This is the first sentence.</s>
<s>This is the second sentence.</s>
<s>This is the third <pb n="2"/>sentence.</s>
</p>
<p>
<s>This is the first sentence.</s>
<s>This is the second sentence.</s>
<s>This is the third sentence.</s>
</p>
</body>
</text>
</TEI>
Expected output
<?xml version="1.0" encoding="utf-8"?>
<TEI>
<text>
<body>
<pb n="1"/>
<p>
<s>This is the first sentence.</s>
<s>This is the second sentence.</s>
<s>This is the third <pb n="2"/>
</s>
</p>
</body>
</text>
</TEI>
Restrictions
- uses the Saxon extension function "saxon:evaluate" (so the Saxon library is needed for this)
- takes no care about namespaces
- wrapping into parent node cannot be configured
