Methods

• method GetPosition() as %String

Returns current position in the XML document, as an XPath expression with information on the next non-comment node.

• method MapContent()

• method Reapply(ByRef pXMLStream As %Stream.Object, pIndent As %Boolean = 1) as %Status

• method characters(chars As %Library.String, length As %Library.Integer)

Receive notification of character data inside an element.
By default, do nothing. Application writers may override this method to take specific actions for each chunk of character data (such as adding the data to a node or buffer, or printing it to a file).

chars: The characters.

length: The number of characters to use from the character array.

• method comment(chars As %String, length As %Integer)

Receive notification of comments.
The Parser will call this method to report each occurence of a comment in the XML document.

The application must not attempt to read from the array outside of the specified range.

chars: The characters from the XML document.

length: The number of characters to read from the array.

Exceptions thrown: SAXException - Any SAX exception, possibly wrapping another exception.

• method endElement(uri As %Library.String, localname As %Library.String, qname As %Library.String)

Receive notification of the end of an element.
By default, do nothing. Application writers may override this method in a subclass to take specific actions at the end of each element (such as finalising a tree node or writing output to a file).

uri: The URI of the associated namespace for this element

localname: The local part of the element name

qname: The QName of this element

• method startDocument()

Receive notification of the beginning of the document.
By default, do nothing. Application writers may override this method in a subclass to take specific actions at the beginning of a document (such as allocating the root node of a tree or creating an output file)

• method startElement(uri As %Library.String, localname As %Library.String, qname As %Library.String, attrs As %Library.List)

Receive notification of the start of an element.
By default, do nothing. Application writers may override this method in a subclass to take specific actions at the start of each element (such as allocating a new tree node or writin output to a file).

uri: The URI of the associated namespace for this element

localname: the local part of the element name

qname: the QName of this element

attrs: a list in $List format consisting of a repeating group of attributes.

The format of the repeating group is as follows:

+0 - uri: The URI of the associated namespace for this attribute

+1 - localname: The local part of the name of this attribute

+2 - qname: The QName of this attribute

+3 - type: The type of this attribute ("CDATA", NMTOKEN", "ENTITY", etc.)

+4 - value: The value of this attribute
