This is a bit of a stretch even for in-house authoring systems.

However, at that level the following could be made to yield your
specific example:

\weather\date{20001108}: It's a nice chilly \temp{70F} degrees here
in \location{Chicago}.

Your example was:

: <p xmlns="http://www.w3.org/1999/xhtml">
: <weather xmlns="http://mysite.com/myns">
: <date c="2000-11-8">November 8, 2000</date>: It's a nice chilly <temp
: c="70F">70</temp> degrees here in <location>Chicago</location>.</weather>
: </p>

You get it with a pipeline.

Blank lines can be understood to represent paragraph boundaries.

Syntatic translation(*) yields the SGML version of your document type
where OMITTAG makes it sane not to write the end tag for "weather",
the end being implied by the paragraph boundary if "weather" can only
contain %paraContents.

The SGML is:

<weather><date>20001108</date>: It's a nice chilly <temp>70F</temp>
degrees here in <location>Chicago</location><eos/>

A translator from the SGML version to the XML version of your document
type knows the xmlns values and is swift at expanding the succinct
date and temperature input.

(*) The syntactic translator in my GELLMU project is still under
development.  Information about it is, however, available on the
