Use PHP to read and write XML and DOM. Reading and Writing Extensible Markup Language (XML) in PHP may seem a little scary. In fact, XML and all its related technologies may be terrible, but reading and writing XML with PHP may not necessarily be reading and writing Extensib
Sometimes in the development of the use of JS to load and read XML files, write down to provide reference, here is mainly in two steps to complete:
1,js load XML file
The steps are generally (1), an XML DOM object is established, (2), the load mode is set, asynchronous (rec
This is the fifth short article "WP7 isolated storage series", focusing on real and practical examples with source code, rather than the theory of inventory. Next I will discuss how to read data from isolated storage and save data to isolated storage.

by any commercial organization. Just like the iso7 Layer Model and TCP/IP, although Sax is not a formal standard, it does not affect its position in the XML parsing field. The principle of Dom implementation is to read the entire XML document at one time and put it in a tree structure. When necessary, find a specific node and then

The code is as follows:
If (file_exists ('test1. XML') {// read the xml file$ Xml = simplexml_load_file ('test1. X
One, what is the purpose of xml,xml?
XML (extensible Markup Language) extends the markup language, which, like HTML, is SGML (Standard generalized Markup Language, the standardized universal Markup language). XML is a cross-platform, content-dependent technology in an Internet environment, and is a powerful tool for th
First, the basic introduction
There are many ways to parse XML, including sax and Dom, and it is highly recommended in Android to parse XML in Xmlpull mode. Xmlpull not only can be used on Android as well as Javase, but in javase environments it is necessary to get the Xmlpull-dependent class library, Kxml2-2.3.0.jar,xmlpull_1_1_3_4c.jar.

3. in JAVA, the java JDK provides XML Parsing: Org. w3c. dom. *, which is SUN's implementation of w3c specifications. However, the efficiency is not high enough. Therefore, we often use third-party components, such as dom4j, with relatively higher efficiency.

Basic features of XMLQ: What is XMLXML is an Extensible Markup language, and XML is a simple data storage language.Q: Briefly describe the common areas and advantages of XMLXML has the characteristics of separation of content and structure, strong interoperability, standardization and support of many coding formats, and it is because of these advantages that XML has been applied in many fields such as data

Reading and writing Extensible Markup Language (XML) in PHP may seem a bit scary. In fact, XML and all of its related technologies can be scary, but reading and writing XML in PHP is not necessarily a scary task.

Before converting data, the data format must support
When reading XML, xmldocument and xelement should put the entire XML file into the memory for operations. This operation is simple, but it is very memory-intensive.And I/O (may be disk I/O or network I/O)In some scenarios, we must consider saving as much memory as possible.And Io overheadIn this caseXmlreaderAnd xmlwriter.
