70 | =head1 NAME | |||
71 | ||||
72 | XML::LibXML::Literal - Simple string values. | |||
73 | ||||
74 | =head1 DESCRIPTION | |||
75 | ||||
76 | In XPath terms a Literal is what we know as a string. | |||
77 | ||||
78 | =head1 API | |||
79 | ||||
80 | =head2 new($string) | |||
81 | ||||
82 | Create a new Literal object with the value in $string. Note that " and | |||
83 | ' will be converted to " and ' respectively. That is not part of the XPath | |||
84 | specification, but I consider it useful. Note though that you have to go | |||
85 | to extraordinary lengths in an XML template file (be it XSLT or whatever) to | |||
86 | make use of this: | |||
87 | ||||
88 | <xsl:value-of select=""I'm feeling &quot;sad&quot;""/> | |||
89 | ||||
90 | Which produces a Literal of: | |||
91 | ||||
92 | I'm feeling "sad" | |||
93 | ||||
94 | =head2 value() | |||
95 | ||||
96 | Also overloaded as stringification, simply returns the literal string value. | |||
97 | ||||
98 | =head2 cmp($literal) | |||
99 | ||||
100 | Returns the equivalent of perl's cmp operator against the given $literal. | |||
