.SH "NAME"
HTML::Microformats::Utilities \- utility functions for searching and manipulating HTML
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module includes a few functions for searching and manipulating \s-1HTML\s0 trees.
.ie n .IP """searchClass($class, $node, [$prefix])""" 4
.el .IP "\f(CWsearchClass($class, $node, [$prefix])\fR" 4
.IX Item "searchClass($class, $node, [$prefix])"
Returns a list of elements which are descendents of \f(CW$node\fR and have class name \f(CW$class\fR.
.Sp
\&\f(CW$class\fR can be a plain string, or a regular expression.
.Sp
If \f(CW$prefix\fR is supplied it is used as an optional prefix for \f(CW$class\fR. For example, with \f(CW$class\fR 'bar'
and \f(CW$prefix\fR 'foo', searchClass will look for all of the following classes: 'bar', 'foobar', 'foo\-bar'
and 'foo:bar'.
.ie n .IP """searchAncestorClass($class, $node, [$skip])""" 4
.el .IP "\f(CWsearchAncestorClass($class, $node, [$skip])\fR" 4
.IX Item "searchAncestorClass($class, $node, [$skip])"
Returns the first element which is an ancestor of \f(CW$node\fR having class name \f(CW$class\fR.
.Sp
\&\f(CW$class\fR can be a plain string, or a regular expression.
.Sp
\&\f(CW$skip\fR is the number of levels of ancestor to skip. If \f(CW$skip\fR is 0, then potentially searchAncestorClass
will return \f(CW$node\fR itself. If \f(CW$skip\fR is 1, then it will not return \f(CW$node\fR but could potentially return
its parent, and so on.
.ie n .IP """searchRel($relationship, $node)""" 4
.el .IP "\f(CWsearchRel($relationship, $node)\fR" 4
.IX Item "searchRel($relationship, $node)"
Returns a list of elements which are descendents of \f(CW$node\fR and have relationship \f(CW$relationship\fR.
.Sp
\&\f(CW$relationship\fR can be a plain string, or a regular expression.
.ie n .IP """searchRev($relationship, $node)""" 4
.el .IP "\f(CWsearchRev($relationship, $node)\fR" 4
.IX Item "searchRev($relationship, $node)"
As per searchRel, but uses the rev attribute.
.ie n .IP """searchID($id, $node)""" 4
.el .IP "\f(CWsearchID($id, $node)\fR" 4
.IX Item "searchID($id, $node)"
Returns a descendent of \f(CW$node\fR with id attribute \f(CW$id\fR, or undef.
.ie n .IP """searchAncestorTag($tagname, $node)""" 4
.el .IP "\f(CWsearchAncestorTag($tagname, $node)\fR" 4
.IX Item "searchAncestorTag($tagname, $node)"
Returns the nearest ancestor of \f(CW$node\fR with tag name \f(CW$tagname\fR, or undef.
.ie n .IP """stringify($node, \e%options)""" 4
.el .IP "\f(CWstringify($node, \e%options)\fR" 4
.IX Item "stringify($node, %options)"
Returns a stringified version of a \s-1DOM\s0 element. This is conceptually equivalent
to \f(CW\*(C`$node\->textContent\*(C'\fR, but follows microformat-specific stringification
rules, including value excerption, the abbr pattern and so on.
.ie n .IP """xml_stringify($node)""" 4
.el .IP "\f(CWxml_stringify($node)\fR" 4
.IX Item "xml_stringify($node)"
Returns an \s-1XML\s0 serialisation of a \s-1DOM\s0 element. This is conceptually equivalent
to \f(CW\*(C`$node\->toStringEC14N\*(C'\fR, but hides certain attributes which
HTML::Microformats::DocumentContext adds for internal processing.
