Summary: Invalid element names in document
Initial Comment:
I can build a new document with invalid element names.
Example:
<root>
<1_depth>Element at depth: 1
<2>Element at depth: 2
<depth_3>Element at depth: 3</depth_3>
</2>
</1_depth>
</root>
Elements '1_depth' and '2' are not valid names becouse
they start with a number.
Element Naming Convention:
XML elements must follow these naming rules:
* Names can contain letters, numbers, and other
characters
* Names must not start with a number or punctuation
character
* Names must not start with the letters xml (or XML
or Xml ..)
* Names cannot contain spaces

Query1: document.selectNodes("//1_depth")
Throws the exception: org.dom4j.InvalidXPathException:
Invalid XPath expression: //1_depth Unexpected '1'

org.dom4j.xpath.DefaultXPath.parse(DefaultXPath.java:315)

org.dom4j.tree.AbstractNode.createXPath(AbstractNode.java:205)
at
org.dom4j.tree.AbstractNode.selectNodes(AbstractNode.java:161)
Query2: document.selectNodes("//depth_3") works well
being a child of an invalid parent element names.
Thanks,
