XML::LibXML::Attr(3) User Contributed Perl Documentation XML::LibXML::Attr(3)NAMEXML::LibXML::Attr - XML::LibXML Attribute Class
SYNOPSIS
$attr = XML::LibXML::Attr->new($name [,$value]);
$string = $attr->getValue();
$string = $attr->value;
$attr->setValue( $string );
$node = $attr->getOwnerElement();
$attr->setNamespace($nsURI, $prefix);
$bool = $attr->isId;
$string = $attr->serializeContent;
DESCRIPTION
This is the interface to handle Attributes like ordinary nodes. The
naming of the class relies on the W3C DOM documentation.
new
$attr = XML::LibXML::Attr->new($name [,$value]);
Class constructor. If you need to work with ISO encoded strings,
you should always use the createAttrbute of XML::LibXML::Document.
getValue
$string = $attr->getValue();
Returns the value stored for the attribute. If undef is returned,
the attribute has no value, which is different of being not speci-
fied.
value
$string = $attr->value;
Alias for getValue()
setValue
$attr->setValue( $string );
This is needed to set a new attribute value. If ISO encoded strings
are passed as parameter, the node has to be bound to a document,
otherwise the encoding might be done incorrectly.
getOwnerElement
$node = $attr->getOwnerElement();
returns the node the attribute belongs to. If the attribute is not
bound to a node, undef will be returned. Overwriting the underlying
implementation, the parentNode function will return undef, instead
of the owner element.
setNamespace
$attr->setNamespace($nsURI, $prefix);
This function tries to bound the attribute to a given namespace. If
$nsURI is undefined or empty, the function discards any previous
association of the attribute with a namespace. If the namespace was
not previously declared in the context of the attribute, this func-
tion will fail. In this case you may wish to call setNamespace() on
the ownerElement. If the namespace URI is non-empty and declared in
the context of the attribute, but only with a different (non-empty)
prefix, then the attribute is still bound to the namespace but gets
a different prefix than $prefix. The function also fails if the
prefix is empty but the namespace URI is not (because unprefixed
attributes should by definition belong to no namespace). This func-
tion returns 1 on success, 0 otherwise.
isId
$bool = $attr->isId;
Determine whether an attribute is of type ID. For documents with a
DTD, this information is only available if DTD loading/validation
has been requested. For HTML documents parsed with the HTML parser
ID detection is done automatically. In XML documents, all "xml:id"
attributes are considered to be of type ID.
serializeContent($docencoding)
$string = $attr->serializeContent;
This function is not part of DOM API. It returns attribute content
in the form in which it serializes into XML, that is with all meta-
characters properly quoted and with raw entity references (except
for entities expanded during parse time). Setting the optional
$docencoding flag to 1 enforces document encoding for the output
string (which is then passed to Perl as a byte string). Otherwise
the string is passed to Perl as (UTF-8 encoded) characters.
