XPath is a language used to search for information in XML documents. XPath can be used to traverse elements and attributes in XML documents. XPath is the main element of W3C XSLT standards, and XQuery and XPointer are also built on XPath expressions. We recommend a pretty good site: there are good examples in the http:

Recently I was studying a DRP project. The database driver string and URL string are written into the configuration file to increase program flexibility. You need to use dom4j and XPath technology to read the data. The following describes common XPath knowledge. XPath uses path expressions to select nodes or node sets in XML documents. Nodes are selected by fol

I have also sent a message about. net, but it is not very detailed. Now I will introduce in detail how to operate XML files in C #, just like learning to operate a database and learn the SQL language, before learning to operate XML and the language, we need to familiarize ourselves with the XML "SQL" Statement XPath.
