is //book[author="Neal Stephenson"]/title/text() .Now I provide a simple program that executes the query from the Java language and prints out the titles of all the books found. First, you need to load the document into a DOM Document object. For simplicity, assume that the document is in the Books.xml file in the current working directory. The following simple code snippet parses the document and establishes the corresponding Document object:Listing 3. Parsing documents with JAXP Docume
= DocumentBuilderFactory.newInstance(); factory.setNamespaceAware(true); // never forget this! DocumentBuilder builder = factory.newDocumentBuilder(); Document doc = builder.parse("books.xml");
So far, this is just the standard JAXP and Dom, nothing new.
CreateXPathFactory:
XPathFactory factory = XPathFactory.newInstance();
Then use this factory to createXPathObject:
Research on XPath injection attack and its defense technology

Summary XML technology is widely used, and the security of XML data is more and more important. This article briefly introduces the principle of XPath injection attacking XML data. On the basis of the common defense methods proposed by predecessors,
PHP uses xpath to parse XML, and xpath to parse xml
This example describes how PHP parses XML using xpath. We will share this with you for your reference. The details are as follows:
XML files are widely used in lightweight applications developed by PHP websites. There are many ways for PHP to parse and read XML files, such as js dom, SimpleXml, and
A simple understanding of some basic methods for operating XPath in JavaScript, and how to operate xpath in javascript
Xpath is rarely used now, because JSON is very popular now. However, when XML was used as the data exchange format, Xpath played a very important role when we randomly accessed the large xml document s

The core idea of XPath design: quickly navigate to the element (or node) you need. After the PHP file i
XPath data type
XPath can be divided into four types of data:
Node Set (node-set)
A node set is a set of nodes that match the criteria returned by a path. Other types of data cannot be converted to node sets.
Boolean Value (Boolean)
A conditional matching value returned by a function or Boolean expression, the same as a Boolean value in the general language, with true and false two values. Boolean values c
XPath Data Type
XPath can be divided into four data types:
Node-set)
A node set is a set of nodes that meet the conditions returned by path matching. Other types of data cannot be converted to a node set.
Boolean)
The condition matching value returned by a function or Boolean expression is the same as the Boolean value in a general language and has two values: true and false. Boolean values can be converte
XPath summary this tutorial describes how to search for information in the XML document. You have learned how to use XPath to navigate through elements and attributes in the XML document. You also learned how to apply some built-in scale functions in XPath.

1. Scenario Mode
When discussing the factory method mode, I mentioned an application framework for exporting data, but I didn't discuss how to implement each method for exporting text. Now let's solve this problem.Assume that the exported file is divided into three parts, the file header, the end of the file, and the file body, regardless of the format.Document Header: Number of the branch or outlet, date of data exportEnd of file: outputFile body: Table NameExport data to text files and XML fil
ASP. net2.0 has been systematically studied recently. Watch the msdn WebCASE video tutorial "ASP. net2.0 Quick Start" (Thank you, Mr Su Peng :)). This section describes the use of the xmldatasource control. Create a page, drag and drop an xmldatasource control, bind an online XML file as the data source, drag a formview control, edit the template itemtemplate, drag two labels, and set data binding, use the XPath expression to obtain the "title" and "D
XPath can quickly navigate to a node or attribute in the XML. The XPath syntax is simple, but powerful enough, and it is also the basic knowledge of using XSLT.Sample xml:

In XPath, there are seven types of nodes: elements, attributes, text, namespaces, processing commands, comments, and document nodes (or become root nodes ). In XPath, Node has seven types of nodes: elements, attributes, and text.
