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.

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");
