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. Since this series of posts does not aim to introduce t

Use the following XML document to describe the XPath Syntax: Locate a node:The XML document can be viewed as a node tree (similar to a computer tree folder ).XPath uses pattern expressions to recognize nodes in XML documents. An XPATH mode is a list of child element names separated by diagonal lines to describe a path

When using dom4j, we cannot obtain an element across layers. it must be obtained at one layer, which is very troublesome. Why xpath? When using dom4j, we cannot obtain an element across layers. it must be obtained at one layer, which is very troublesome.Therefore, we can use the xpath technology to access a node more conveniently, which allows us to conveniently read the specified node.

this:This XML file represents the reseller. The dealer is a node, and the dealer "inside" is a node that represents the onboard inventory. The dealer is the "parent" of the car node, and the car node is the "child". Then there are branches underneath the car node that produce the "Kids" node. Each vehicle node forms a "sibling" relationship. In this example, there is a tree-multi-attribute relationship. property enables the intrinsic characteristics of a particular node. You'll notice that each

XPath is the XML query language, which is similar to SQL. The XML below is used as an example to introduce the XPath syntax. Locate a node XML is a tree structure, similar to the structure of the data folder in the file system. XPath is similar to the path naming method in the file sys
