DOM XML enhancement proposal

Hi! I am using php 4.0.6 distribution. I need to use libxslt library, so I've written a patch for DOM XML extension. Besides I've added some functions available in libxml2 and not present in PHP. This is the list of added features: * htmldoc and htmldocfile functions (xmldoc and xmldocfile for HTML format) * domxml_htmldumpmem function (domxml_dumpmem for HTML format) * libxslt_applyxsl function (using libxslt; for XSLT transformations) * better error handling for mentioned functions * [ICONV]: better error handling for iconv function - DOM XML extension requires libxslt to compile, but I had no time to implement separate extension (I know this is wrong) Could someone take a look at the patch I've attached (maybe correct it) and merge it to the CVS? Perhaps someone did the same work? Regards, Jaroslaw Kolakowski
