I think there are two basic approaches to this kind of problem. One is to
convert the punctuation into tags, and then manipulate the resulting tree
structure; the other is to turn the embedded tags into punctuation (like
"[emphasis]two[/emphasis]") and then manipulate the content as a character
string. My instinct, like Martin Honnen's, is to do the first.
There are still complications, of course. For example if you're detecting
end-of-sentence as [.?!] followed by a space or end-of-paragraph, then it's
challenging to handle the case where the [.?!] is the last character in a text
node but the text node isn't the last thing in the paragraph. (For example
"sentence.<footnote>x</footnote> "). There's no easy answer to this (and
natural language being what it is, there is no right answer either).

Hi All,
I have a situation where I want to split a short paragraph into sentences and
use them in different parts of my output. I am using <xsl:analyze-string>
because I want to account for a sentence ending with a . or ?. This will work
except if there are any children of the paragaph, like the <emphasis> in the
second sentence. Can I split a paragraph into sentences and still keep the
markup?
Here is my input document:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<p>This has one sentence? Actually, it has <emphasis>two</emphasis>. No,
it has three.</p>
</root>
My stylesheet:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform
<http://www.w3.org/1999/XSL/Transform>"

<xsl:template match="/root">
<xsl:copy>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="p">
<xsl:variable name="sentences"
select="rq:splitParagraphIntoSentences(.)"/>
<p><xsl:value-of select="$sentences[1]"/></p>
<note>Something in between.</note>
<p><xsl:value-of select="$sentences[position()>1]"/></p>
</xsl:template>
<xsl:function name="rq:splitParagraphIntoSentences">
<xsl:param name="paragraph"/>
<xsl:analyze-string select="$paragraph" regex=".+?[\.\?](\s+|$)">
<xsl:matching-substring>
<sentence><xsl:value-of
select="replace(.,'\s+$','')"/></sentence>
</xsl:matching-substring>
</xsl:analyze-string>
</xsl:function>
</xsl:stylesheet>
My output:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<p>This has one sentence?</p>
<note>Something in between.</note>
<p>Actually, it has two. No, it has three.</p>
</root>
What I want is this:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<p>This has one sentence? </p>
<note>Something in between.</note>
<p>Actually, it has <emphasis>two</emphasis>. No, it has three. </p>
</root>
Any suggestions will be appreciated.
