Re: Breaking paragraphs one linebreaks

Dear all,

I'm impressed and very thankful for all your answers. I'll try to address
all your comments:

@Martin, your example works really well. I had to edit the expression, as
in my real files sometimes they have used lists instead of linebreaks:

<xsl:param name="lb" as="xs:string">&lt;/?(li|ul|br)\s*/?&gt;</xsl:param>

However, I can see what I would also need to split at the end of sentences
when there's no escaped tag but just final punctuation. To avoid the
transformation eating the punctuation, I have tried with a lookbehind
assertion but it seems it's not supported:

<xsl:param name="lb"
as="xs:string">(?<=[.!?])\s|&lt;/?(li|ul|br)\s*/?&gt;</xsl:param>

Any ideas?

@Gerrit, I think I can use XSLT 2.0 or XSLT 3.0 (I have downloaded Saxon HE
9.9), but I'm not sure what you mean with your second question. Ther'e
might be leading and trailing tags in the text, but <seg> is the text node,
there are no further elements inside <seg>

@Eliot, thanks for that reference. It would be intersting to see what line
breaking does. Are there any examples I can look at?

Thank you so much again!

Cheers, Manuel
