&reftitle.required; &libxml.required; This extension uses an expat compat layer by default. It can use also expat, which can be found at &url.expat;. The Makefile that comes with expat does not build a library by default, you can use this make rule for that: A source RPM package of expat can be found at &url.expat.rpm;.

&reftitle.resources; Prior to PHP 8.0.0, the xml resource as returned by xml_parser_create and xml_parser_create_ns referenced an xml parser instance to be used with the functions provided by this extension.
