RSS2.0标准

什么是RSS？RSS是一种网页内容联合格式（web content sydication format）。

它的名字是Really Simple Syndication的缩写。

RSS是XML的一种。

所有的RSS文档都遵循XML 1.0规范，该规范发布在W3C网站上。

在一个RSS文档的开头是一个<rss>节点和一个规定的属性version，该属性规定了该文档将以RSS的哪个版本表示。

如果该文档以这个规范来表示，那么它的version属性就必须等于2.0。

在<rss>节点的下一级是一个独立的<channel>节点，该节点包含关于channel的信息和内容。

关于本文档该文档是在2002年秋天撰写的，当时的RSS版本为2.0.1。

它包含从RSS 0.91规范(2000年)开始的所有的修改和添加，以及包含在RSS 0.92（2000年12月）和RSS 0.94（2002年8月）中的新的特性。

必需的频道节点下面有一份必须包含的频道(channel)节点的列表，每一个都有一个简单的描述、一个例子、应该出现的位置和更详细描述的超链接。

可选的频道元素下面是可选的频道元素列表<channel>子节点<image><image>是一个可选的<channel>子节点，该节点包含三个必需的子元素和三个可选的子元素。

<url>是GIF、JPEG或PNG图像文件的URL地址，该图像代表整个频道<title>用于描述上面的图像，等同于HTML语言中的<img>的alt属性<link>是要连接的站点的url，当显示频道时，图像的连接指向该站点。

<title>和<link>应该与频道的<title>和<link>有相同的值可选的节点包括<width>和<height>，它们是数字类型，指定图像的宽度和高度，单位为像素<description>就是link的TITLE属性中文本，它将在调用网页时显示出来。

RSS协议

RSS协议RSS是在线共享内容的一种简易方式（也叫聚合内容），通常在时效性比较强的内容上使用RSS订阅能更快速获取信息，网站提供RSS输出，有利于让用户获取网站内容的最新更新。

RSS 2.0 概述那么RSS究竟代表什么呢？比较普遍的有两种说法，一种是“Rich Site Summary”或“RDF Site Summary”，另一种是“Really Simple Syndication”，之所以有这些分歧，需要从RSS发展的历史说起。

最初的0.90版本RSS是由Netscape公司设计的，目的是用来建立一个整合了各主要新闻站点内容的门户，但是0.90版本的RSS规范过于复杂，而一个简化的RSS 0.91版本也随着Netscape公司对该项目的放弃而于2000年暂停。

不久，一家专门从事博客写作软件开发的公司UserLand接手了RSS 0.91版本的发展，并把它作为其博客写作软件的基础功能之一继续开发，逐步推出了0.92、0.93和0.94版本。

随着网络博客的流行，RSS 作为一种基本的功能也被越来越多的网站和博客软件支持。

在 UserLand公司接手并不断开发RSS的同时，很多的专业人士认识到需要通过一个第三方、非商业的组织，把RSS发展成为一个通用的规范，并进一步标准化。

于是2001年一个联合小组在0.90版本RSS 的开发原则下，以W3C新一代的语义网技术RDF（Resource Description Framework）为基础，对RSS进行了重新定义，发布RSS1.0，并将RSS定义为“RDF Site Summary”。

但是这项工作没有与UserLand公司进行有效的沟通，UserLand公司也不承认RSS 1.0的有效性，并坚持按照自己的设想进一步开发出RSS 的后续版本，到2002年9月发布了最新版本RSS 2.0，UserLand公司将RSS定义为“Really Simple Syndication”。

RSS使用指南范文

RSS使用指南范文RSS（通用订阅文聚合）是一种用于获取和整合各种网络资源的技术，包括博客文章、新闻、音频、视频等等。

通过使用RSS，用户可以通过一个统一的界面或应用程序订阅他们感兴趣的内容，并在更新时自动接收通知。

本文将介绍RSS的基础知识并提供使用指南。

1.什么是RSS？RSS是一种用于发布和订阅网络内容的标准格式。

它使用XML（扩展标记语言）来描述内容，以及用于存储和传输的RSS文档。

RSS文档通常包含标题、描述、链接和发布日期等元数据，以及内容的文本或摘要。

2.如何使用RSS？首先，您需要一个RSS阅读器或聚合器来订阅和查看RSS源。

有很多不同的阅读器可供选择，包括在线服务、桌面应用程序和移动应用程序。

一些流行的阅读器包括Feedly、Inoreader、Digg Reader等。

3.如何找到和订阅RSS源？可以通过以下几种方法找到和订阅RSS源：-直接从您感兴趣的网站查找RSS图标或链接。

通常，网站会在首页、文章页或订阅页面上提供RSS订阅选项。

-使用引擎特定领域或主题的RSS源。

例如，“科技新闻RSS”将返回一系列与科技新闻相关的RSS源链接。

-参考其他人的推荐或分享，他们可能已经发现了一些好的RSS源并将其共享给大家。

4.如何添加和管理RSS源？添加RSS源通常很简单。

在大多数阅读器中，只需复制RSS源的链接地址，然后粘贴到阅读器的订阅或添加源选项中即可。

阅读器将解析源的内容，并在您的阅读器中显示更新。

为了更好地管理您的RSS源，您可以创建不同的文件夹或类别，以将源组织在一起。

rss源_精品文档

rss源RSS源是一种在互联网上广泛使用的技术，用于获取最新的网站内容并将其推送给用户。

RSS源（Really Simple Syndication）通过XML格式存储信息，通常用于博客、新闻网站和其他更新频率较高的网站，使用户可以方便地获取最新的内容，而无需定期访问网站。

RSS源的工作原理非常简单。

网站所有者可以将其内容整理成RSS格式，并将其发布到一个特定的文件上，称为RSS源。

这个文件包含了网站的标题、摘要和链接等信息。

用户通过使用一个叫做RSS阅读器的应用程序来订阅这些RSS源。

RSS阅读器会周期性地检查订阅的RSS源，如果有新的内容发布，它就会自动将这些内容推送给用户。

用户可以根据自己的兴趣订阅多个RSS源，以便获取多个网站的最新内容。

RSS源的一个重要优点是它可以提供个性化的内容订阅体验。

用户可以根据自己的兴趣和偏好选择订阅哪些RSS源，从而获取自己感兴趣的内容。

相比传统的浏览器书签或收藏夹，RSS源提供了一种更加高效的方式来获取更新的内容，并避免了不必要的广告和其他干扰。

另一个重要的优点是RSS源的及时性。

通过订阅RSS源，用户可以第一时间获取到最新的内容。

无论是新闻、博客文章还是其他类型的更新，RSS源都可以帮助用户保持与网站的同步，而无需花费大量时间去搜索或浏览。

除了个人用户，许多企业和组织也使用RSS源来传播信息。

对于新闻机构、博客作者和市场营销人员来说，通过发布RSS源，他们可以更好地与受众建立联系，并增加自己的曝光度。

通过RSS源，他们可以将最新的信息推送给用户，并吸引更多的访问者或潜在客户。

然而，尽管RSS源具有许多优点，但它也存在一些挑战和限制。

首先，许多网站尚未提供RSS源，这意味着用户无法通过RSS阅读器订阅这些网站的内容。

此外，RSS源的质量也存在差异。

一些RSS源可能包含不准确或过时的信息，这会影响用户获取可靠的内容。

最后，由于大量的信息更新，用户可能会在阅读过程中感到压倒，无法有效地处理所有的内容。

贴片电阻090阻值

贴片电阻090阻值
贴片电阻的阻值通常是通过颜色编码或数字编码来表示的。

如
果是通过颜色编码，通常使用的是四色环编码系统，每个颜色代表
一个数字，通过排列组合可以得到电阻的阻值。

另一种常见的编码
方式是数字编码，即直接在电阻上标注阻值的数字。

在这两种编码
方式下，090阻值的含义是：
首先，如果是颜色编码，"0"代表黑色，"9"代表棕色，"0"代表
黑色。

因此，090阻值对应的颜色编码为黑色、棕色、黑色，根据
四色环编码系统，这个电阻的阻值为009欧姆。

其次，如果是数字编码，090直接表示电阻的阻值为90欧姆。

总的来说，贴片电阻090阻值可以表示为009欧姆或者90欧姆，具体取决于使用的编码方式。

希望这个回答能够满足你的需求。
