Reading a XML document embeeded in a logfile

I have a scenario where one thread or process will keep on creating
XML documents and append it in a logfile.
Another thread might be interested in reading the XML documents from
the log file sequentially.
The problem is if the logfile has two XML documents then the file content
will become an invalid document.
I can introduce a root element called Logfile and append all the documents
as a child. But whenever I append a XML document I have to reposition
the pointer to rewrite XML document root tag.
Is there any way I can instruct the parser not to read the complete file,
but read the file upto the first element A and its contents and next it has
to return second element and its content. Parser.readStream( ) is giving
error when it finds a scenario like this because it reads the whole file.
Is it possible to create Document node from a "XML Document String in
memory" instead of stream or file.
Basically I like to use XML for a logfile where either I should be able to
embed the XML document within the logfile, or multiple XML documents
will be appended to the logfile continously and I must be able to read the
XML docs one by one, or I want to read the embeded XML document into
memory and parse it to Document node.
Any idea will be appreciated. Thanks for your time.
