Javascript 读取 XML String 或 XML File_js读xml string-优快云博客

本文介绍了一个简单的函数，该函数能够将XML字符串转换为XML文档类型，便于使用AJAX进行操作。文中提供了JavaScript代码示例，并展示了如何利用此函数解析XML字符串。

function listAllStates()
{ 

var xmlDoc;
var xmlString = '<states><state>wei</state></states>';

    // Mozilla and Netscape browsers
    if (document.implementation.createDocument) {
        var parser = new DOMParser()
        xmlDoc = parser.parseFromString(xmlString, "application/xml")
    // MSIE
    } else if (window.ActiveXObject) {
        xmlDoc = new ActiveXObject("Microsoft.XMLDOM")
        xmlDoc.async="false"
        xmlDoc.loadXML(xmlString)
    }
   

  var x = xmlDoc.getElementsByTagName('state');

  alert (xmlDoc);
  alert (x.length);
}
 
 listAllStates();

I created a very basic function which allows you to convert XML in a string type, into an XML Document type, which gives you the benefits of XML with AJAX.

I'll write up a better explanation another time, as well as submit some other useful data conversion functions

<script type="text/javascript">
// Name: createXMLDocument
// Input: String
// Output: XML Document
jQuery.createXMLDocument = function(string)
{
var browserName = navigator.appName;
var doc;
if (browserName == 'Microsoft Internet Explorer')
{
doc = new ActiveXObject('Microsoft.XMLDOM');
doc.async = 'false'
doc.loadXML(string);
} else {
doc = (new DOMParser()).parseFromString(string, 'text/xml');
}
return doc;
}
</script>

Usage:

<script type="text/javascript">
var text = '<message><from>me</from><to>you</to></message>';
var doc = $.createXMLDocument(text);
</script>
