dom4j question XPath and concurrent transactions
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 Grosman
