甘肃农大附近酒店:xpath提取超链

来源：百度文库编辑：查人人中国名人网时间：2024/05/08 13:30:27

想问一下，我想从一下这个xml文件中利用xpath提取出从文件最后数倒数第二个href的属性值，请问该怎么写 <xsl:for-each select="//body/table/tbody/td='1'......>中的......？我很着急，不知哪个高手能帮助我？谢谢啦！
（以下是xml文件）

这是XML嘛？
把你的的XML文件和你的解析XML的那个基类粘出来我看下

xpath提取超链利用xpath提取超链的问题超链提取技术疑问超链提取技术疑问 XPath主要功能是什么？关于xml的xpath 超临界提取色素和膜技术提取色素有什么区别？当前XPath标准的状态是什么？ XPath是哪个组织的标准？为什么有些信用卡只能透支2000元,只能提取400元,要是超了怎么办??
