javascript加载并解析xml

<mce:script type="text/javascript"><!--var xmlDoc;//加载xml文件function loadXMLDoc(file){xmlDoc = null;try{xmlDoc=new ActiveXObject("Microsoft.XMLDOM");}catch(e){try{xmlDoc=document.implementation.createDocument("","",null);}catch(e){alert(e.message);return;}}//关闭异步加载,确保在文档完全加载之前解析器不会继续脚本的执行xmlDoc.async=true;xmlDoc.load(file);return xmlDoc;}//解析xml文件function parseXMLDoc(){var dataArr = xmlDoc.getElementsByTagName("SCHMADATA_row");if(dataArr.length > 0){var fieldArr = dataArr[0].childNodes;var fieldNameArr = new Array(fieldArr.length);for(var j=0; j<fieldArr.length; j++){fieldNameArr[j] = fieldArr[j].nodeName;}alert(fieldNameArr)}}// --></mce:script>

可执行程序

<input type="file" id="xml_path" name="xml_path" value="" onchange="loadXMLDoc(this.value)"/><input type="button" value="view" name="解析文件" onclick="parseXMLDoc();"/>
