用javascript读xml的例子
1.xml文件如下：
<?xml version="1.0" encoding="UTF-8"?><zip><city>mycity</city><state>mystate</state></zip>
2.读此xml的javascript例子：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title><script language="javascript" type="text/javascript">
var url = "NewFile.xml"; String.prototype.Trim = function() { return this.replace(/(^/s*)|(/s*$)/g, ""); }
var xmlDoc;
var moz = (typeof document.implementation != 'undefined') && (typeof document.implementation.createDocument != 'undefined'); var ie = (typeof window.ActiveXObject != 'undefined');
function importXML(file) {
if (moz) { xmlDoc = document.implementation.createDocument("", "doc", null);
} else if (ie) { xmlDoc = new ActiveXObject("MSXML2.DOMDocument.3.0"); xmlDoc.async = false; while(xmlDoc.readyState != 4) {}; } xmlDoc.load(file);}importXML(url);
function updateCityState(){if (moz) { var zip = xmlDoc.getElementsByTagName("zip")[0]; var city; var _city = zip.getElementsByTagName("city")[0].firstChild.nodeValue; if (_city) city = _city.Trim(); var state; var _state=zip.getElementsByTagName("state")[0].firstChild.nodeValue; if(_state) state = _state.Trim();
document.getElementById('city').value = city; document.getElementById('state').value = state; } else if (ie) { var city; var _city = xmlDoc.selectSingleNode("/zip/city"); if (_city) city = _city.text; var state; var _state=xmlDoc.selectSingleNode("/zip/state"); if(_state) state = _state.text; document.getElementById('city').value = city; document.getElementById('state').value = state; } }</script></head><body><form action="post">
<p> ZIP code: <input type="text" size="5" name="zip" id="zip" οnblur="updateCityState();" />
</p> City: <input type="text" name="city" id="city" />
State: <input type="text" size="2" name="state" id="state" />
</form></body></html>
