NAME
       XML::LibXML::Common - Routines and Constants common for XML::LibXML and
       XML::GDOME

SYNOPSIS
         use XML::LibXML::Common;

DESCRIPTION
       XML::LibXML and XML::GDOME share some of the same functionality. This
       package should bundle some shared constansts and functions, so both
       modules may coexist within the same scripts.

       XML::LibXML::Common defines all node types as constants. While
       XML::LibXML and XML::GDOME originally declared their own node type
       definitions, one may want to use XML::LibXML::Common in its
       compatibility mode:

       +o   use XML::LibXML::Common qw(:libxml);

           :libxml will use the XML::LibXML Compatibility mode, which defines
           the old 'XML' node-type definitions

       +o   use XML::LibXML::Common qw(:gdome);

           This allows one to use the XML::LibXML Compatibility mode, which
           defines the old 'GDOME' node-type definitions

       +o   use XML::LibXML::Common qw(:w3c);

           This uses the nodetype definition names as specified for DOM.

       +o   use XML::LibXML::Common qw(:encoding);

           This is ment if only the encoding functions of XML::LibXML::Common
           should be used.

       By default the W3 definitions as defined in the DOM specifications and
       the encoding functions are exported by XML::LibXML::Common.

       To encode or decode a string to or from UTF-8 XML::LibXML::Common
       exports two functions, which use the encoding mechanism of the
       underlaying implementation. These functions should be used, if external
       encoding is required (e.g. for queryfunctions).

       eennccooddeeTTooUUTTFF88

           $encodedstring = encodeToUTF8( $nameofencoding, $stingtoencode );

       The function will encode a string from the specified encoding to UTF-8.

       ddeeccooddeeFFrroommUUTTFF88

           $decodedstring = decodeFromUTF8($nameofencoding, $stringtodecode );

       This Function transforms an UTF-8 encoded string the specified
       encoding.  While transforms to ISO encodings may cause errors if the
       given stirng contains unsupported characters, both functions can
       transform to UTF-16 encodings as well.

       Note that both encoding functions report their errors on the standard
       error. If an error occours the function will croak(). To catch the
       error information it is required to call the encoding function from
       within an eval block to avoid a script to stop.
