Determine the location - file \& line number of an (internal) XML node
getLineNumber function is used to query the location of an internal/C-level
XML node within its original "file". This gives us the line number.
getNodeLocation gives both the line number and the name of the
file in which the node is located, handling XInclude files in a
top-level document and identifying the included file, as appropriate.

combining the file and line number into a string and ignoring the
This is useful when we identify a node with a particular charactestic and want to view/edit the original document, e.g. when authoring an Docbook article.

getLineNumber returns an integer.
getNodeLocation returns a list with two elements -
line which are a character string
and the integer line number.
For text nodes, the line number is taken from the previous sibling nodes or the parent node.
