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. Tidy or even better CyberNeko may be a useful work around. In particular X2V uses XSLT, and tidy to clean any non-well-formed input before processing it.

Parsing class values

When parsing class values care must be taken:

  1. Class attributes may contain multiple class names, e.g: class="foo vcard bar"
  2. Class attributes may contain class names which contain the class name used by a microformat, e.g: class="foovcardbar" class="foovcard", class="vcardbar".
  3. Multiple class names are seperated by one or more whitespace charchters.
  4. Class names are case sensitive.

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

JavaScript example

The Ultimate getElementsByClassName JavaScript function may be useful. Then you can do:

var adrs = document.getElementsByClassName(document, "*", "adr");

or even:

var cities = document.getElementsByClassName(document, "*", "locality");

XSLT example

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

xpath generator, to help you generate those long ugly xpath queries. [link broken as of 8 August 2006]

Parsing rel/rev values

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

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