XML for PHP developers Part 1: advanced technology for reading, manipulating, and writing XML

Introduction PHP5 provides developers with more tools to process xml (standardization is getting closer and closer. New and modified extensions such as DOM, Simplexml (standardization is getting closer and closer), and XSL greatly compress the code to be written to process xml (standardization is getting closer and closer. DOM in PHP5 complies with W3C standards. Most importantly, these extensions have strong interoperability and therefore provide more features, such as extensibility through interchange formats.

PHP5 provides developers with more tools to process xml (standardization is getting closer and closer. New and modified extensions such as DOM, Simplexml (standardization is getting closer and closer), and XSL greatly compress the code to be written to process xml (standardization is getting closer and closer. DOM in PHP5 complies with W3C standards. Most importantly, these extensions are highly interoperable and provide more features, such as extended availability, W3C XPath, and more comprehensive features through interchange formats. Here you will see the input and output options, relying on the Yahoo Web Service REST protocol interface to provide a more complex display for the well-known DOM and Simplexml (standardization is getting closer and closer) extensions, finally, we will discuss the XSL extension.

Content review

The first article in this series introduces the basic knowledge of xml (standardization is getting closer and closer. This section mainly introduces simple entry-level application programming interfaces (APIs). For example, it illustrates Simplexml (standardization is getting closer and closer) for simple, predictable, and small xml documents) (sometimes used in conjunction with the Document Object Model (DOM) is an ideal technology. Part 2 provides a horizontal introduction to the parsing xml (standardization is getting closer and closer) API provided in PHP5, including Simplexml (standardization is getting closer and closer), DOM, Simple API for xml (standardization is getting closer and closer) (SAX) and xml (standardization is getting closer and closer) Reader, this article discusses which parsing technology is most appropriate for xml documents of different sizes and complexity (standardization is getting closer and closer.

Xml in PHP5 (standardization is getting closer and closer)

The Extensible Markup Language (xml (standardization is getting closer and closer) is not just a markup language, but also a text-based data storage format, provides a text-based tree structure for applications and descriptions. Below we will see the xml in the Web service context (standardization is getting closer and closer), maybe this is one of the most important factors driving xml (standardization is getting closer and closer) growth outside of the enterprise.

PHP5 provides all-new and fully-rewritten xml (standardization is getting closer and closer) operation extensions, all based on the same libxml (standardization is getting closer and closer) 2 code. This public Foundation provides interoperability for these extensions and extends their respective functions. Tree-based parser includes Simplexml (standardization is getting closer and closer), DOM and XSLT processing programs. If you are familiar with DOM in other languages, it is easier to use PHP to implement similar functions. Stream-based resolvers include Simple API for xml (standardization is getting closer) (SAX) and xml (standardization is getting closer and closer) Reader. The functions of SAX are the same as those of PHP4.
