用ASP和Microsoft.XMLDOM分析远程XML文件

用xmldom方法打开xml文件,如果是本地的没有问题,就是用Server.MapPath("xml.xml")的方法,这时能正常分析出内容,但是直接用url却不显示出xml内容(在XMLDOM里表示是支持URL方式的),后来研究一下发现可以用XMLHTTP的方法获取XML后再分析,代码如下:

Set http=Server.CreateObject("Microsoft.XMLHTTP")
http.Open "GET"," http://www.site.com/xml.xml",False
http.send

Set xml=Server.CreateObject("Microsoft.XMLDOM")
xml.Async=False
xml.ValidateOnParse=False
xml.Load(http.ResponseXML)
If xml.ReadyState>2 Then
Response.Write("文档已经准备就绪。状态:"& xml.ReadyState &"

1<br/>

")
Set item=xml.getElementsByTagName("item")
For i=0 To (item.Length-1)
Set title=item.Item(i).getElementsByTagName("title")
Set link=item.Item(i).getElementsByTagName("link")
Response.Write("

1<a "&="" &"""="" href="" link.item(0).text="">"&amp; title.Item(0).Text &amp;"</a>
1<br/>

")
Next
Else
Response.Write("文档还未准备就绪。状态:"& xml.ReadyState &"

1<br/>

")
End If
Set http=Nothing
Set xml=Nothing

xml.xml文档的内容如下:

 1<channel>
 2<item>
 3<title>测试文档1</title>
 4<link/>http://localhost/   
 5</item>
 6<item>
 7<title>测试文档2</title>
 8<link/>http://localhostindex.asp   
 9</item>
10</channel>
