XML::LibXML's DOM parser is not only capable to parse XML data, but also
118
118
(strict) HTML files. There are three ways to parse documents - as a string, as
119
a Perl filehandle, or as a filename/URL. The return value from each is a L<<<<<< XML::LibXML DOM Document Class|XML::LibXML DOM Document Class >>>>>> object, which is a DOM object.

All of the functions listed below will throw an exception if the document is

XML::LibXML provides some functions to serialize nodes and documents. The
417
serialization functions are described on the L<<<<<< Abstract Base Class of XML::LibXML Nodes|Abstract Base Class of XML::LibXML Nodes >>>>>> manpage or the L<<<<<< XML::LibXML DOM Document Class|XML::LibXML DOM Document Class >>>>>> manpage. XML::LibXML checks three global flags that alter the serialization

XML::LibXML throws exceptions during parsing, validation or XPath processing
