Hello,
I am very new to dom4j, in fact I am sending this
message,
for a "where to start" query.
I need to implement concurrent transactions on an
XML database.
the transaction are given to me in XPath
expressions,
so all I need to do is to evaluate the _expression_ (
already found a way to do this in one of dom4j examples ).
My question is , how do I apply 2PL Tree locking
algorithm (Read and Write locks) on dom4j's XPath query algorithm ?
please help, any kind of help would help a lot !
sorry again, if what I am asking is so trivial,
Thank you
