- the following line works like expected:
\splitstring{http://some.net}\at://\to\protocol\and\tail
I get the protocol type in \protocol and the rest in \tail.
- given an XML file with a line like
<ulink url="http://some.net">...</ulink>
applying the follwoing:
\splitstring\XMLpar{ulink}{url}{}\at://\to\protocol\and\tail
does not work like expected. Instead I get the whole URL in \protocol
and \tail is mpty
Any hints?
Michael

Catcode problem, probably. What about the following:
\splitstring{\scantokens{\XMLpar{ulink}{url}{}}}\at://\to\protocol\and\tail
or
\expandafter\splitstring\expandafter{\scantokens{\XMLpar{ulink}{url}{}}}\at://\to\protocol\and\tail

beware, scantokens adapts to the current catcode regime; when a macro is
loaded it's kind of frozen, so then a \ is still a \, while in xml mode,
the \ is something different, so here scantokens would read the data as
being xml (unless xml mode is temporary disables).
I guess that this fuzzy explanation will make you go into the tex source
code -)

No, it just drives me mad for this crazy expansion/catcode mechanism of
TeX 8-)

actually, in itself catcodes are a nice concept, but there should have been
provisions to push / pop states (too slow in macros)

\expanded{\splitstring\XMLpar{ulink}{url}{}}\at....
^^^^^^^^^ ^
this will expand the XMLpar before feeding it to the splitter; the first
token in \expanded is not expanded.
