Result = XMLNodeFromPath(ParentNode, Path$)Description
Returns the XML node inside ParentNode who's relation to ParentNode is described through 'Path$'. XMLNodePath() can be used to get such a path to a node.
ParentNode The parent XML node. Path$ Contains a list of node names separated by '/' to indicate the way to follow from the parent to the target node. For example "childtag/subchildtag" specifies the first node with name "subchildtag" inside the first node with name "childtag" inside ParentNode.
A node name can have an index (one based) to specify which of multiple child tags of the same name should be selected. "childtag/subchildtag" specifies the 3rd "subchildtag" inside the first "childtag" of ParentNode.
- If a path starts with '/' it is relative to the tree's root. No matter which node ParentNode specifies.
- A Wildcard "*" can be used instead of a tag name to specify that any tag is to be selected.
- A Comment node has the tagname "#comment"
- A Processing Instruction node has the tagname "#instruction"
Some examples of valid paths:"/mainnode/#comment" - the 4th comment inside the "mainnode" node inside the root of the tree "*" - the 10th node (of any type) inside ParentNode "*/*/*" - the 1st node 3 levels below ParentNode independent of its typeNote: This command is no implementation of the XPath specification. The syntax used and understood by this command is only a small subset of XPath. This means a path returned from XMLNodePath() is a valid XPath query, but this command only understands the syntax described here, not just any XPath query.
The target node or zero if the path did not lead to a valid node.
