Its of course Access denied to achieve theproperty Element.childNodes, and not firstNode. 表达式没有意义,getElementsByTagName给出一个 集合,你可以索引,而childNodes给你一个集合,你可以索引。 我认为你应该向我们展示XML你加载并描述你要读出的元素 ,然后我们可以帮助编码对这些元素的访问。That expression does not make sense, getElementsByTagName gives acollection which you can index, and childNodes gives a collection whichyou can index too.I think you should show us the XML you load and describe the elementsyou want to read out, then we can help coding the access to those elements. 好的。实际上我只想提取1个数字(1或0)所以我只需要XML中的1 值。我的XML如下: <?xml version =" 1.0" encoding =" iso-8859-1"?> < nick> < isa> 0< / isa> < / nick> 我正在尝试获取元素的值< isa> HushOk. Actually I only want to extract 1 number (1 or 0) so I only need 1value from the XML.
