NAME
XML::Smart::DTD - DTD parser for XML::Smart. DESCRIPTION
This will parse DTD and provides methods to access the information stored in the DTD. USAGE
use XML::Smart::DTD ; my $dtd = XML::Smart::DTD->new('some.dtd') ; if ( $dtd->child_exists('tag1','subtag1') ) { ... } use Data::Dumper ; print Dumper( $dtd->tree ) ; new METHODS
attr_exists ( TAG , ATTR ) Return TRUE if the attribute exists in the element TAG. child_exists ( TAG , CHILD ) Return TRUE if the child exists in the element TAG. elem_exists ( TAG ) Return TRUE if the element TAG exists. error Return the error list. get_attr_def ( TAG , ATTR ) Return the default value of an attribute get_attr_type ( TAG , ATTR ) Return the attribute type. get_attr_values ( TAG , ATTR ) Return the defined values of an attribute. get_attrs ( TAG ) Return the attribute list of a element. get_attrs_req ( TAG ) Return the required attribute list of a element. get_childs ( TAG ) Return the child list of an element. get_childs_req ( TAG ) Return the required child list of an element. get_elem_opt ( TAG ) Return the occurrence option of an element: ! REQUIRED AND ONLY ONE MATCH + 1 or more * 0 or more ? 0 or 1 get_elem_child_opt ( TAG , CHILD ) Same of get_elem_opt() but this element as a child of an element. is_attr_fix ( TAG , ATTR ) Return TRUE if an attribute is FIXED. is_attr_req ( TAG , ATTR ) Return TRUE if an attribute is REQUIRED. is_elem_any ( TAG ) Return TRUE if an element is ANY. is_elem_child_multi ( TAG , CHILD ) Return TRUE if an element can have multiple occurrences as a child of TAG. is_elem_child_opt ( TAG , CHILD ) Return TRUE if an element is optional as a child of TAG. is_elem_child_req ( TAG , CHILD ) Return TRUE if an element is optional as a child of TAG. is_elem_child_uniq ( TAG , CHILD ) Return TRUE if an element is required and unique as a child of TAG. is_elem_pcdata ( TAG ) Return TRUE if an element is PCDATA (have content). is_elem_empty ( TAG ) Return TRUE if an element is EMPTY (doesn't have attributes, content or children). is_elem_multi ( TAG ) Return TRUE if an element can have multiple occurrences globally. is_elem_opt ( TAG ) Return TRUE if an element is optional globally. is_elem_parent ( TAG , @PARENTS ) Return TRUE if the list of @PARENTS can be parent of element TAG. is_elem_req Return TRUE if an element is required globally. is_elem_uniq Return TRUE if an element is unique and required globally. root Return the root name of the DTD. tree Return the HASH tree of the DTD.

NAME
XML::DOM::Element - An XML element node in XML::DOM DESCRIPTION
XML::DOM::Element extends XML::DOM::Node. By far the vast majority of objects (apart from text) that authors encounter when traversing a document are Element nodes. Assume the fol- lowing XML document: <elementExample id="demo"> <subelement1/> <subelement2><subsubelement/></subelement2> </elementExample> When represented using DOM, the top node is an Element node for "elementExample", which contains two child Element nodes, one for "subele- ment1" and one for "subelement2". "subelement1" contains no child nodes. Elements may have attributes associated with them; since the Element interface inherits from Node, the generic Node interface method getAt- tributes may be used to retrieve the set of all attributes for an element. There are methods on the Element interface to retrieve either an Attr object by name or an attribute value by name. In XML, where an attribute value may contain entity references, an Attr object should be retrieved to examine the possibly fairly complex sub-tree representing the attribute value. On the other hand, in HTML, where all attributes have simple string values, methods to directly access an attribute value can safely be used as a convenience. METHODS getTagName The name of the element. For example, in: <elementExample id="demo"> ... </elementExample> tagName has the value "elementExample". Note that this is case-preserving in XML, as are all of the operations of the DOM. getAttribute (name) Retrieves an attribute value by name. Return Value: The Attr value as a string, or the empty string if that attribute does not have a specified or default value. setAttribute (name, value) Adds a new attribute. If an attribute with that name is already present in the element, its value is changed to be that of the value parameter. This value is a simple string, it is not parsed as it is being set. So any markup (such as syntax to be recognized as an entity reference) is treated as literal text, and needs to be appropriately escaped by the implementation when it is written out. In order to assign an attribute value that contains entity references, the user must create an Attr node plus any Text and EntityReference nodes, build the appropriate subtree, and use setAttributeNode to assign it as the value of an attribute. DOMExceptions: * INVALID_CHARACTER_ERR Raised if the specified name contains an invalid character. * NO_MODIFICATION_ALLOWED_ERR Raised if this node is readonly. removeAttribute (name) Removes an attribute by name. If the removed attribute has a default value it is immediately replaced. DOMExceptions: * NO_MODIFICATION_ALLOWED_ERR Raised if this node is readonly. getAttributeNode Retrieves an Attr node by name. Return Value: The Attr node with the specified attribute name or undef if there is no such attribute. setAttributeNode (attr) Adds a new attribute. If an attribute with that name is already present in the element, it is replaced by the new one. Return Value: If the newAttr attribute replaces an existing attribute with the same name, the previously existing Attr node is returned, otherwise undef is returned. DOMExceptions: * WRONG_DOCUMENT_ERR Raised if newAttr was created from a different document than the one that created the element. * NO_MODIFICATION_ALLOWED_ERR Raised if this node is readonly. * INUSE_ATTRIBUTE_ERR Raised if newAttr is already an attribute of another Element object. The DOM user must explicitly clone Attr nodes to re-use them in other elements. removeAttributeNode (oldAttr) Removes the specified attribute. If the removed Attr has a default value it is immediately replaced. If the Attr already is the default value, nothing happens and nothing is returned. Parameters: oldAttr The Attr node to remove from the attribute list. Return Value: The Attr node that was removed. DOMExceptions: * NO_MODIFICATION_ALLOWED_ERR Raised if this node is readonly. * NOT_FOUND_ERR Raised if oldAttr is not an attribute of the element. Additional methods not in the DOM Spec setTagName (newTagName) Sets the tag name of the Element. Note that this method is not portable between DOM implementations. DOMExceptions: * INVALID_CHARACTER_ERR Raised if the specified name contains an invalid character. check ($checker) Uses the specified XML::Checker to validate the document. NOTE: an XML::Checker must be supplied. The checker can be created in different ways, e.g. when parsing a document with XML::DOM::ValParser, or with XML::DOM::Document::createChecker(). See XML::Checker for more info. perl v5.8.8 2008-02-03 XML::DOM::Element(3pm)
