MicahDubinko: Still a bug in the XPath, cleaning it up and making the structure more evident

= Parsing Microformats =

Microformat parsing mechanisms that depend on documents having even minimal xml properties like well-formedness may fail when consuming non-well-formed content. [http://tidy.sourceforge.net/ Tidy] or even better [http://people.apache.org/~andyc/neko/doc/html/ CyberNeko] may be a useful work around.
In particular [http://suda.co.uk/projects/X2V/ X2V] uses XSLT, and [http://tidy.sourceforge.net/ tidy] to clean any non-well-formed input before processing it.

== Parsing class values ==

When parsing class values care must be taken:
# Class attributes may contain multiple class names, e.g: <code>class="foo vcard bar"</code>
# Class attributes may contain class names which contain the class name used by a microformat, e.g: <code>class="foovcardbar"</code> <code>class="foovcard"</code>, <code>class="vcardbar"</code>.
# Multiple class names are seperated by one or more whitespace charchters.
# Class names are case sensitive.

See http://www.w3.org/TR/html401/struct/global.html#h-7.5.2.

=== JavaScript example ===
The [http://www.robertnyman.com/2005/11/07/the-ultimate-getelementsbyclassname/ Ultimate getElementsByClassName] JavaScript function may be useful. Then you can do:

<code>
var adrs = document.getElementsByClassName(document, "*", "adr");
</code>

or even:

<code>
var cities = document.getElementsByClassName(document, "*", "locality");
</code>

=== XSLT example ===
<code>
<xsl:if test="contains(
concat (' ', normalize-space(@class),' '),
' vcard '
)" > ...
</code>

== Parsing rel/rev values ==

Parsing rel and rev values is similar to parsing class values except for the following differences:

# rel and rev values should be separated by one space.
# rel and rev values are case insensitive.

See http://www.w3.org/TR/html401/types.html#type-links.
