【100分】用VB6 实现XML 文档的修改保存
本帖最后由 fosm0131 于 2012-12-05 09:36:36 编辑 小弟有如下一个XML file,现在想实现功能：利用form1上的textbox 控件里输入数值，并替换xml file中相应的内容（红色字段)，最后那部分的矩阵大小需要改变，（现在是21x21，可能需要改成 N×M,N M是任意正的整数).
有哪位大侠可以给点代码或者启示？xml file 有点长，高分重谢！

[解决办法]
定位节点的语法叫 XPath
函数 SelectNodes(XPath) 取得一批节点
函数 SelectSingleNode(XPath) 取得一个节点
Google 之
XML 中一批节点无特征区分就可以等同对待。
你可以随意替换；或者全面删除旧的节点，然后插入自己新的节点。
[解决办法]
引用xml,代码中loadXML，得到xml对象，剩下的就是selectnodes和selectsinglenode找节点(可用Xpath语法来找)，找到后赋给xmlelement对象，对它的值或属性修改了
