Hi.

Been playing with this a lot this weekend.  Thanks to #axkit-dahut for
their help.

*Anyway*, I've made some changes to the Template::Plugin::XML::XPath
plugin that effects the way that it supports rendering out undefined tags
with views.  Previously the examples in the plugin pod would render the
whole thing straight through as a string.  This is okay, but breaks for
things like

   <p>This is some <red>red</red> text</p>

Where <p> hasn't been defined.  As everything including and below <p> is
rendered as a string I literally get

   <p>This is some <red>red</red> text</p>

Back again rather than <red> being processed though

  [% BLOCK red %]<font color="red">[% item.content(view) %]</font>[% END %]

To give

  <p>This is some <font color="red">red</font> text</p>

So I made some changes.  This involved having T::P::XML::XPath add
"starttag" and "endtag" methods to XML::XPath::Node::Element so that
the default handling for xmlstring (unknown tags) is now

[% BLOCK xmlstring; item.starttag; item.content(view); item.endtag; END %]

This is all covered in the attached diff.

Oh, I also added some "| html" filters to the examples too (as the output
of XML::XPath will have converted &amp; to & already so you need to
convert them back again).

Later.

Mark.
