Google SiteMap的作用及协议格式详解
Google SiteMap PRotocol是Google自己推出的一种站点地图协议,此协议文件基于早期的robots.txt文件协议,并有所升级。在Google官方指南中指出加入了Google SiteMap文件的网站将更有利于Google网页爬行机器人的爬行索引,这样将提高索引网站内容的效率和准确度。文件协议应用了简单的xml格式,一共用到6个标签,其中关键标签包括链接地址、更新时间、更新频率和索引优先权。
Google SiteMap文件生成后格式如下:
<urlset xmlns="http://www.google.com/schemas/sitemap/0.84"> <url> <loc>http://www.knowsky.com</loc> <lastmod>2005-06-03T04:20-08:00</lastmod> <changefreq>always</changefreq> <priority>1.0</priority> </url> <url> <loc>http://www.knowsky.com/300687.html</loc> <lastmod>2005-06-02T20:20:36Z</lastmod> <changefreq>daily</changefreq> <priority>0.8</priority> </url> </urlset>XML标签
changefreq:页面内容更新频率。
lastmod:页面最后修改时间
loc:页面永久链接地址
priority:相对于其他页面的优先权
url:相对于前4个标签的父标签
urlset:相对于前5个标签的父标签
我将一句一句分解讲解这个xml文件的每一个标签:
字符 转义后的字符 HTML字符 字符编码
and(和) & & &
单引号 ' ' '
双引号 " " "
大于号 > > >
小于号
年:YYYY(2005)
年和月:YYYY-MM(2005-06)
年月日:YYYY-MM-DD(2005-06-04)
年月日小时分钟:YYYY-MM-DDThh:mmTZD(2005-06-04T10:37+08:00)
年月日小时分钟秒:YYYY-MM-DDThh:mmTZD(2005-06-04T10:37:30+08:00)
还有和,这两个就是来关闭xml标签的,这和HTML中的和

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.
