XmlReader.getPath() should include the element position in a list of elements

[sockeqwe]

When generating error messages XmlReader.getPath() doesn't display the position of the element that has caused the error is part of a list with sibling elements.

Example:

<foo>
   <bar attr="123" />
   <bar attr="CausesErrorBecauseNotInteger" />
</foo>

then the error message should print /foo/bar[1] (1 is the index/position of the element in the list, starting at 0) as path and not just /foo/bar as it is right now. Makes debugging easier, because we know which element (in the list of elements) has caused this issue.
