4th Dimension developers are sometimes reluctant to work with DOM because writing tree navigation code can seem complicated. The XML Tools component documented in Technical Note 07-25 includes a module of routines starting with the string “XmlTreeWalker” that automate scanning a DOM tree. This code effectively flattens the tree and makes it easier to deal with for developers more used to serial data structures, such as arrays, lists, and selections of records. This Technical Note provides additional background information about the XmlTreeWalker system and its use.

As with Technical Note 07-25, this Technical Note includes the XML Tools component, the source code database used to create the component, and an example database that shows many of the component's features at work.
