我正在尝试读取文件并更新XML。现在我正在尝试使用HTML5 API和DOMParser来实现它，但我遇到了一些麻烦。
<script>
function handleFileSelect(evt) {
var files = evt.target.files; // FileList object
// Loop through the FileList
for (var i = 0, f; f = files[i]; i++) {
var reader = new FileReader();
parser=new DOMParser();
// Closure to capture the file information.
reader.onload = (function(theFile) {
return function(e) {
// Print the contents of the file
// var span = document.createElement('span');
xmlDoc=parser.parseFromString(e.target.result,"text/xml");
try{
DistributomeXML_Objects=xmlDoc.documentElement.childNodes;
}catch(error){
DistributomeXML_Objects=xmlDoc.childNodes;
}
// document.getElementById('list').insertBefore(span, null);
};
})(f);
// Read in the file
//reader.readAsDataText(f,UTF-8);
reader.readAsText(f);
}
//xmlDoc.getElementsByTagName("distributome").item(0).appendChild(node);
traverseXML(false, null, DistributomeXML_Objects, distributome.nodes, distributome.edges, distributome.references, distributomeNodes, referenceNodes);
}
document.getElementById('files').addEventListener('change', handleFileSelect, false);
</script>
我从
获得了一些线索HTML5 File api, reading in an xml/text file and displaying it on the page?
和我之前的问题

我认为我的代码中存在错误，导致XML文档无法创建，我无法发现它，并会感激任何帮助。
