.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module provides simple whitespace striping and text-node
normalizing functions.
.ie n .SS """trim($string)"""
.el .SS "\f(CWtrim($string)\fP"
.IX Subsection "trim($string)"
Returns the string with any whitespace occuring at its beginning or
end removed.
.ie n .SS """xml_normalize($dom)"""
.el .SS "\f(CWxml_normalize($dom)\fP"
.IX Subsection "xml_normalize($dom)"
Puts all Text nodes in the full depth of the sub-tree underneath this
Element into a normal form where only markup (e.g., tags,
comments, processing instructions, \s-1CDATA\s0 sections, and entity
references) separates Text nodes, i.e., there are no adjacent Text
nodes. This can be used to ensure that the \s-1DOM\s0 view of a document is
the same as if it were saved and re-loaded, and is useful when
operations (such as XPointer lookups) that depend on a particular
document tree structure are to be used.
.ie n .SS """xml_strip_whitespace($dom [,$include_attributes])"""
.el .SS "\f(CWxml_strip_whitespace($dom [,$include_attributes])\fP"
.IX Subsection "xml_strip_whitespace($dom [,$include_attributes])"
Normalizes the subtree and trims whitespace from all Text nodes within
the subtree. If the optional argument \f(CW$include_attributes\fR is defined
and non-zero, this function trims whitespace also from all Attribute
nodes.
.ie n .SS """xml_strip_element($node)"""
.el .SS "\f(CWxml_strip_element($node)\fP"
.IX Subsection "xml_strip_element($node)"
Removes leading and trailing whitespace from a given element.
