        "METHODS": {
            "content": "The class inherits from XML::LibXML::Node. The documentation for Inherited methods is not listed\nhere.\n\nMany functions listed here are extensively documented in the DOM Level 3 specification\n(<http://www.w3.org/TR/DOM-Level-3-Core/>). Please refer to the specification for extensive\ndocumentation.\n\nnew\n$attr = XML::LibXML::Attr->new($name [,$value]);\n\nClass constructor. If you need to work with ISO encoded strings, you should *always* use the\n\"createAttribute\" of XML::LibXML::Document.\n\ngetValue\n$string = $attr->getValue();\n\nReturns the value stored for the attribute. If undef is returned, the attribute has no\nvalue, which is different of being \"not specified\".\n\nvalue\n$string = $attr->value;\n\nAlias for *getValue()*\n\nsetValue\n$attr->setValue( $string );\n\nThis is needed to set a new attribute value. If ISO encoded strings are passed as parameter,\nthe node has to be bound to a document, otherwise the encoding might be done incorrectly.\n\ngetOwnerElement\n$node = $attr->getOwnerElement();\n\nreturns the node the attribute belongs to. If the attribute is not bound to a node, undef\nwill be returned. Overwriting the underlying implementation, the *parentNode* function will\nreturn undef, instead of the owner element.\n\nsetNamespace\n$attr->setNamespace($nsURI, $prefix);\n\nThis function tries to bound the attribute to a given namespace. If $nsURI is undefined or\nempty, the function discards any previous association of the attribute with a namespace. If\nthe namespace was not previously declared in the context of the attribute, this function\nwill fail. In this case you may wish to call setNamespace() on the ownerElement. If the\nnamespace URI is non-empty and declared in the context of the attribute, but only with a\ndifferent (non-empty) prefix, then the attribute is still bound to the namespace but gets a\ndifferent prefix than $prefix. The function also fails if the prefix is empty but the\nnamespace URI is not (because unprefixed attributes should by definition belong to no\nnamespace). This function returns 1 on success, 0 otherwise.\n\nisId\n$bool = $attr->isId;\n\nDetermine whether an attribute is of type ID. For documents with a DTD, this information is\nonly available if DTD loading/validation has been requested. For HTML documents parsed with\nthe HTML parser ID detection is done automatically. In XML documents, all \"xml:id\"\nattributes are considered to be of type ID.\n",

                    "content": "$string = $attr->serializeContent;\n\nThis function is not part of DOM API. It returns attribute content in the form in which it\nserializes into XML, that is with all meta-characters properly quoted and with raw entity\nreferences (except for entities expanded during parse time). Setting the optional\n$docencoding flag to 1 enforces document encoding for the output string (which is then\npassed to Perl as a byte string). Otherwise the string is passed to Perl as (UTF-8 encoded)\ncharacters.\n"
