New page

This is a proof-of-concept that it is possible to keep track of partial metrical lines (encoded with <tt>part=I</tt>, <tt>M</tt>, and <tt>F</tt> — this demo knows nothing of <tt>part=Y</tt> or <tt>N</tt>, nor <tt>next=</tt> and <tt>prev=</tt>, nor <tt><join></tt>) using XSLT 1.0. As the internal documentation says, I bet there’s a better way to do this. I’m kinda hoping that by posting here someone will replace this with an improved version. (In which case, please just replace the content of this page, rather than make a new one.)

NB that I will post [[an XSLT 2.0 version]] soon, which is much simpler

<xd:p>This is just a proof-of-concept stylesheet that counts the nubmers

<xd:p>Does not process <tt>&lt;l></tt> descendants, so if you had couplets encoded,
this stylesheet wouldn't do much useful</xd:p>
<xd:p>This is only intended to demonstrate that this <xd:b>can</xd:b> be done in
XSLT 1.0, not ot demonstrate a good way to do it. Quite the reverse — my
plan is to post this to XSL-LIST and ask “what’s the right way to do this”?, since
this clearly isn’t.</xd:p>
