Answer 1

代码没错，应该是你的XML文档不合法，用IE打开看看行不行

Answer 2

图片好像发不上去直接给出错误信息的链接吧：http://d.namipan.com/img/14a5475b572621022757a2a91cce4a199c7da83e9644070060f6

Answer 3

还真是头疼
那句出的异常?
你图片中的代码与楼上的代码不一样似的,
怀疑你的
xmnode := ...findnode...;
这一句根本没取到,所以后边的showMessage报非法访问

Answer 4

node:=xml.DocumentElement; 
这句异常我的xml
