phpHtmllib is a set of PHP classes and library functions to help facilitate building, debugging, and rendering of XML, HTML, XHTML WAP/WML Documents, and SVG (Scalable Vector Graphics) images as well as complex html 'widgets'. It provides a mechanism to output perfectly indented/readable XML/HTML/XHTML/WML/SVG source, and a programmatic API to generating XML/HTML/XHTML/WML/SVG on the fly.

Features
PHP classes and functions to build XML/HTML/XHTML/WML/SVG tags.
Every XML/HTML/XHTML/WML/SVG tag is a PHP class. Common, standardized API for building tags, their attributes, and adding content to the tag (object).
Renders nicely indented XML/HTML/XHTML/WML/SVG source code, for easy reading/debugging. To see this in action, view source on this page.
Powerful "Debugging" capability - The lib renders a viewable version of source code in color-coded output. This also includes links in the source code view on certain tag's attribute values. For example, click the "DEBUG this page" link to view the debug feature built into the classes. NOTICE this is NOT just a header directive for Content-Type: text/plain. ALSO: There are clickable links on the href attribute, as well as src attribute. This can be helpful for debugging pages.
