XML format for tree grids

I have looked through the web site, but cannot find the an XML example for loading a tree grid. It seems you hide any useful XML examples by just saying loadXML(“tree.xml”)! Where is the “tree.xml” so I can see it? That goes for the other XML examples as well. Thank you.

The online samples doesn’t include the viewable xml, but it can be fetched directly, for example
    dhtmlx.com/docs/products/kb/inde … =yes&s=xsd

Also , dhtmlxTreeGrid package contains code of all samples with related HTML files.
