"This project is effectively a [PHP 4] library class for reading/writing/displaying XML documents, for manipulating them in memory by adding/deleting/changing attribute values and child nodes, and for extracting specific nodes from larger XML objects. It is written entirely in PHP (as a file to "require"), and depends on no other software, tools, libraries etc. ... it does not conform to the Document Object Model (DOM), which is the formal standard for XML memory representations. This project is meant only to be more useful than nothing at all."
