sadam.dom A Document Object Model (DOM) interface for Max. sadam.dom will create, read, store or even modify DOM trees. The DOM is one of the possible representations of the contents of an XML document (see http://www.w3.org/TR/DOM-Level-2-Core/.) The object internally uses the default Java DOM parser that comes as an instance of javax.xml.parsers.DocumentBuilderFactory, bringing all the power and almost all of the functionality of a W3C-certified DOM parser to MaxMSP. The kind of Nodes currently not handled by sadam.dom are: Comment, Entity, EntityReference, Notation and ProcessingInstruction. When an XML is parsed, the object will assign a unique ID to each Element of the document, called the Element Index. This index won't get stored and changes each time when the order of Elements in the XML is modified (either by inserting or removing Elements). However, using the Element Index is the preferred (and in most cases, the only) way to address a given element in the XML. The Element Index is sent out the rightmost outlet each time an element is accessed. The Element Index of the Document Element is always 0, the rest of the Elements get their index in their 'order of appearence'. This means that even if an Element is being inserted or removed, the Index of the Elements that come earlier in the Document won't change. When querying Attributes, Text, or CDATA nodes, the requested data will be sent out the appropriate outlets in right-to-left order (in case of Attributes, if more than one Attribute is requested, they will be sent to the output as a sequence like AttributeName1-AttributeValue1-AttributeName2-AttributeValue2-...-AttributeNameN-AttributeValueN, alternating on the appropriate outlets) followed by an error code. When querying Elements, the result will be sent out as a sequence (from right to left) consisting of the Element Index, the Tree Depth of the Element (the Document Element is at level 0, its children are at level 1 etc.), the Element's Tag Name, the Attributes, and finally the Text Content (which is a concatenation of all Text and CDATA nodes). The leftmost outlet serves as an error outlet. After each command sent to the object, an error code is being sent back through this outlet at the end of the execution of the given command. A negative value means that the command could not be executed successfully, while 0 means success. In some cases (typically when one or more Elements are queried) the error outlet reports the number of Elements successfully returned. sadam.dom and sadam.sax are both W3C compliant XML parsers, however, this means some overhead in terms of resources. If you need a lightweight, fast XML parser and you can live with some limitations regarding W3C compliance, consider using sadam.rapidXML.
