SimpleXML processing in PHP. Understand the Simplexml (standardization is getting closer and closer) extension bundled with php (as the mainstream development language) version 5, which makes php (as the mainstream development language) the page can understand the Simplexml (standardization is getting closer and closer) extension bundled with php (as the mainstream development language) version 5, which makes php (as the mainstream development language) pages can be queried, searched, modified, and re-published with php (as the mainstream development language) friendly syntax (the standardization is getting closer and closer ).

Php (as the mainstream development language) version 5 introduces Simplexml (standardization is getting closer and closer), a type for reading and writing xml (standardization is getting closer and closer) the new application programming interface (API ). In Simplexml (standardization is getting closer and closer), the following expression:

$ Doc-> rss-> channel-> item-> title

Select an element from the document. As long as you are familiar with the structure of the document, it is easy to write this expression. However, if you do not know where the required elements appear (such as Docbook, HTML, and similar narrative documents), Simplexml (standardization is getting closer and closer) can use XPath expressions to find these elements.

Start to use Simplexml (standardization is getting closer and closer)

Suppose you need a php (as the mainstream development language) page to convert the RSS feed into HTML. RSS is a simple xml (standardization is getting closer and closer) format used to publish chained content. The root element of the document is rss, which contains a channel element. The channel element contains metadata about the feed, such as the title, language, and URL. It also contains various reports encapsulated in the item element. Each item has a link element, including a URL, and a title or description (usually both), including common text. Do not use namespaces.
