XML 和 ASP:检索和解析远程文件 [英] XML and ASP: Retrieve and parse a remote file
问题描述
我正在启用 ASP 的 Windows Server 上构建站点.我需要从另一台服务器检索 XML 文档并在该文档中返回一个值.xml 文件很小 - 只有一个带有文本值的节点.我只需要返回那个文本值.我以前从未使用过 ASP，谷歌搜索让我找到了一些代码示例，但到目前为止还没有任何效果.这是我得到的，它给了我 500:
I'm building a site on a Windows Server with ASP enabled. I need to retrieve an XML document from another server and return a value in that document. The xml file is small - only one node with a text value. I just need to return that text value. I've never worked with ASP before, and Googling around has led me to some code examples, but nothing that works so far. Here's what I've got, which gives me a 500:
<%
Dim URL, objXML
URL = "http://someserver.com/xml"
Set objXML = Server.CreateObject("MSXML2.DOMDocument.4.0")
objXML.setProperty "ServerHTTPRequest", True
objXML.async = False
objXML.Load(URL)
If objXML.parseError.errorCode <> 0 Then
Response.Write(objXML.parseError.reason)
Response.Write(objXML.parseError.errorCode)
End If
Set oRoot = objXML.selectSingleNode("//xml/response")
var = oRoot.text
set objXML = nothing
%>
<%= var %>
============
===========
更新:
是的，您对我的 XML 的看法完全正确.只有一个具有值的节点.根据您的评论，我将我的 asp 代码编辑为:
Yes, you're exactly correct about my XML. Just one node with a value. Based on your comments, I edited my asp code to:
<%
Dim URL, objXML, value
URL = "http://someserver.com/xml"
Set objXML = Server.CreateObject("MSXML2.DOMDocument.6.0")
objXML.setProperty "ServerHTTPRequest", True
objXML.async = False
objXML.Load URL
Response.Write objXML.parseError.reason
value = objXML.documentElement.Text
set objXML = nothing
%>
<%= value %>
仍然返回 500.我该如何调试 ASP?有什么方法可以开启详细的错误报告吗?
Which is still returning a 500. How do I go about debugging ASP? Is there some way to turn on detailed error reporting?
推荐答案
我写了这个函数:
<%
Option Explicit
Response.Buffer = True
Dim xml
Set xml = Server.CreateObject("Microsoft.XMLDOM")
xml.async = False
xml.setProperty "ServerHTTPRequest", True
xml.Load ("http://www.midominio.com/nombre.xml")
Dim title, heading, paragraph, testHTML
title = xml.documentElement.childNodes(0).text
heading = xml.documentElement.childNodes(1).text
paragraph = xml.documentElement.childNodes(2).text
testHTML = xml.documentElement.childNodes(3).text
Set xml = Nothing
%>
<html>
<head>
<title><%= title %></title>
</head>
<body>
<h3 align="center"><%= heading %></h3>
<p align="center"><% = paragraph %></p>
<div align="center"><%= testHTML %></div>
</body>
</html>
