One of the challenges of working with XML through DOM in 4th Dimension is the difficulty of displaying trees within 4th Dimension. Fortunately, 4th Dimension's hierarchical lists provide a native interface object that can be used to display the structure of an XML tree.  The XML Tools component documented in Technical Note 07-25 includes a module of routines starting with the string XmlTreeList that automate connecting an XML tree and a hierarchical list. This Technical Note provides additional background information about the XmlTreeList 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.
