写了个request2XML的方法,每当数据中有'属性,问题迎刃而解!在XML文档中的所有文本都会被解析器解析。 只有在CDATA部件之内的文本会被解析器忽略。----------------------------------------------------- 解析数据 XML 解析器通常情况下会处理XML文档中的所有文本。 当XML元素被解析的时候,XML元素内部的文本也会被解析:
转义字符不合法的XML字符必须被替换为相应的实体。 如果在XML文档中使用类似"if salary 为了避免出现这种情况,必须将字符"if salary < 1000 then 下面是五个在XML文档中预定义好的实体:
< < 小于号
> > 大于号
& & 和
' ' 单引号
" " 双引号
实体必须以符号"&"开头,以符号";"结尾。 注意: 只有"
CDATA部件在CDATA内部的所有内容都会被解析器忽略。如果文本包含了很多的""标记结束: <script> <![CDATA[ function matchwo(a,b) { if (a < b && a < 0) then { <a href="http://www.php.cn/wiki/135.html" target="_blank">return 1 } <a href="http://www.php.cn/wiki/111.html" target="_blank">else { return 0 } } ]]> </script> 在前面的例子中,所有在CDATA部件之间的文本都会被解析器忽略。 CDATA注意事项: CDATA部件之间不能再包含CDATA部件(不能嵌套)。如果CDATA部件包含了字符"]]>" 或者"字符串"]]>"之间没有空格或者换行符

RSS and XML are tools for web content management. RSS is used to publish and subscribe to content, and XML is used to store and transfer data. They work with content publishing, subscriptions, and update push. Examples of usage include RSS publishing blog posts and XML storing book information.

RSS documents are XML-based structured files used to publish and subscribe to frequently updated content. Its main functions include: 1) automated content updates, 2) content aggregation, and 3) improving browsing efficiency. Through RSSfeed, users can subscribe and get the latest information from different sources in a timely manner.

The XML structure of RSS includes: 1. XML declaration and RSS version, 2. Channel (Channel), 3. Item. These parts form the basis of RSS files, allowing users to obtain and process content information by parsing XML data.

RSS documents work by publishing content updates through XML files, and users subscribe and receive notifications through RSS readers. 1. Content publisher creates and updates RSS documents. 2. The RSS reader regularly accesses and parses XML files. 3. Users browse and read updated content. Example of usage: Subscribe to TechCrunch's RSS feed, just copy the link to the RSS reader.

The steps to build an RSSfeed using XML are as follows: 1. Create the root element and set the version; 2. Add the channel element and its basic information; 3. Add the entry element, including the title, link and description; 4. Convert the XML structure to a string and output it. With these steps, you can create a valid RSSfeed from scratch and enhance its functionality by adding additional elements such as release date and author information.

The steps to create an RSS document are as follows: 1. Write in XML format, with the root element, including the elements. 2. Add, etc. elements to describe channel information. 3. Add elements, each representing a content entry, including,,,,,,,,,,,. 4. Optionally add and elements to enrich the content. 5. Ensure the XML format is correct, use online tools to verify, optimize performance and keep content updated.

The core role of XML in RSS is to provide a standardized and flexible data format. 1. The structure and markup language characteristics of XML make it suitable for data exchange and storage. 2. RSS uses XML to create a standardized format to facilitate content sharing. 3. The application of XML in RSS includes elements that define feed content, such as title and release date. 4. Advantages include standardization and scalability, and challenges include document verbose and strict syntax requirements. 5. Best practices include validating XML validity, keeping it simple, using CDATA, and regularly updating.
