The list strips off attachements so I didn't see your config file.  So I'm
not really clear on what's not working -- I don't see a "hero" tag below.

Swish only does special indexing of HTML titles -- it flags the <title>
words as a title words (for ranking) and adds the words to swishdefault

For xml parsing that doesn't happen, but everything is indexed as
swishdefault (by default).

The same parser is used for XML and HTML parsing.  The difference is that
on tag events some special processing is done with HTML tags, namely that
words are flagged if they are within some tags (e.g. in <title>, <b>,
<em> and so on) and <title> contents are indexed as swishdefault, as
mentioned above.

So, in short, swish gets told when a new tag is found, and then decides
what to do based on if that tag is a set as a ProperyName or MetaName or
other directive.

Now, you can tell swish-e to ignore *everything* inside a <title> tag:

  IgnoreMetaTags title

That will even igonre tags that are defined as MetaNames or PropertyNames
within the tag listed in IgnoreMetaTags.  It really means ignore.

You can also use the UndefinedMetaTags to not index tags that are not
defined by setting UndefinedMetaTags to "ignore".  But, that works best on
HTML files and <meta> tags because in XML everything is a tag.  Plus, as I
just mentioned, with both IgnoreMetaTags and UndefinedMetaTags if a tag is
ignored then everything inside that tag is ignored.  So, in your example
below, if <page> is not listed then nothing will be indexed.

What I think should be done is to make IgnoreMetaTags ignore all content
within that tag, but *if* a tag is listed in MetaNames or PropertyNames
then that should allow indexing.

It's also been suggested that "content" here


should be indexed as the meta name "" instead of just "bar".

I didn't answer your question, probably.  If you have complex XML parsing
needs you may want to use -S prog and a program to parse out the text from
the xml as you like.  It's hard to have a few config directives in swish
that can deal with any structure of an xml file.
