C++读取XML,tinyXml的使用

[来源] 达内    [编辑] 达内   [时间]2012-11-09

最近在开发的过程中,有个需求是对xml进行格式转化,从一种格式转化到另外一种格式.因此,就需要读取xml进行处理.原本打算写成工具在linux下运行,不过后来考虑到和系统结合,最后也就使用了前台js转了.反正都是读取xml,什么技术转不都是一样的么

前言:

< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(68, 68, 68); font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 18px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); ">   最近在开发的过程中,有个需求是对xml进行格式转化,从一种格式转化到另外一种格式.因此,就需要读取xml进行处理.原本打算写成工具在linux下运行,不过后来考虑到和系统结合,最后也就使用了前台js转了.反正都是读取xml,什么技术转不都是一样的么?

< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(68, 68, 68); font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 18px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); ">  不过刚开始还是对要使用的技术做了一定的探究.c++要读取xml有很多种方式.比较又名的有:

< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(68, 68, 68); font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 18px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); ">  rapidXML(这个是网上介绍的,没用过)

< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(68, 68, 68); font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 18px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); ">   Xerces-C++ XML Parser :通常来说,读取XML的方法都是将整个文本进行读取,然后构建成DOM Tree,之后进行遍历等操作.这个Parser除了支持构建DOM Tree的方式之外,还支持类似于回调函数的方式进行处理(SAX,SAX2).在读到相应的节点 然后调用函数进行处理.DOM Tree的方式好处是简单,操作很方便,但是劣势也是很明显:需要把整个XML读进之后才能做处理.如果XML很大,那内存就支撑不住了.SAX,SAX2的作用就在此.其可以支持很大的XML,因为其是相当于事件式的处理方式,不需要构建DOM Tree.不过就是比较麻烦.

< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(68, 68, 68); font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 18px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); ">   TinyXML: 这个就是接下来要介绍的库了.取名Tiny,意在编写一个轻量级的处理基本XML的工具.因此,其支持的特性有限.下面列出了其不支持的功能:

< blockquote style="margin: 10px 0px 10px 25px; padding: 10px 60px 5px; background-image: url(http://common.cnblogs.com/Skins/elf/images/comment.gif); background-color: rgb(255, 255, 255); border: 2px solid rgb(239, 239, 239); color: rgb(51, 51, 51); min-height: 35px; line-height: 1.6em; font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-position: 25px 0px; background-repeat: no-repeat no-repeat; ">

  TinyXML doesn't parse or use DTDs (Document Type Definitions) or XSLs (eXtensible Stylesheet Language.)

                                                           -------------------官方说明文档

< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(68, 68, 68); font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 18px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); ">  其给出的理由也很明确:

< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(68, 68, 68); font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 18px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); ">  1. 支持这两个特性使得库更为庞大

< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(68, 68, 68); font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 18px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); ">  2. 使用更为复杂

< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(68, 68, 68); font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 18px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); ">  3. 学习曲线更曲折

< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(68, 68, 68); font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 18px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); ">  需要使用这些特性的可以考虑上面的xerces-C++ XML Parser.很强大.当然也复杂得多

< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(68, 68, 68); font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 18px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); "> 

< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(68, 68, 68); font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 18px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); ">TinyXml使用:

< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(68, 68, 68); font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 18px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); ">  前言说的已经够多了,咱们就不废话了,直接讲解tinyXml的使用方法.

< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(68, 68, 68); font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 18px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); ">      安装:

< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(68, 68, 68); font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 18px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); ">    TinyXml的安装方法并不复杂,或者说没有安装这个步骤.

< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(68, 68, 68); font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 18px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); ">     1. 下载tinyXml ,下载tinyxml_2_6_2.zip

< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(68, 68, 68); font-family: tahoma, arial, sans-serif; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 18px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); ">    2. 解压unzip tinyxml_2_6_2.zip.(windows就直接解压就可以了)
