'''XML data binding''' refers to a means of representing information in an [[XML]] document as a [[business object]] in computer memory. This allows [[Application software|applications]] to access the data in the XML from the object, rather than using the [[Document Object Model|DOM]] or [[Simple API for XML|SAX]] to retrieve the data from a direct representation of the XML itself.

==Alternatives==

An alternative approach to automatic data binding relies instead on hand-crafted [[XPath]] expressions that extract the data from XML. This approach has a number of benefits. First, the data binding code only needs proximate knowledge (e.g., topology, tag names, etc.) of the XML tree structure, which developers can determine by looking at the XML data; XML schemas are no longer mandatory. Furthermore, XPath allows the application to bind the relevant data items and filter out everything else, avoiding the unnecessary processing that would be required to completely unmarshall the entire XML document. The drawback of this approach is the lack of automation in implementing the object model and XPath expressions. Instead, the application developers have to create these artifacts manually.
