XML

// 读取xml菜单
Ext.Ajax.request({
            url : cfg.menuXml,
            success : function(response, opts) {
                var doc = response.responseXML;
                var rootNode = doc.documentElement || doc;
                // 递归产生树节点
                var createTreeNode = function(node) {
                    var attr = {};
                    for (var i = 0; i < node.attributes.length; i++) {
                        attr[node.attributes[i].name] = node.attributes[i].value;
                    }
                    var treeNode = new Ext.tree.TreeNode(attr);
                    // 递归产生子节点
                    var nodes = Ext.DomQuery.select('/node', node);
                    for (var i = 0; i < nodes.length; i++) {
                        treeNode.appendChild(createTreeNode(nodes[i]));
                    }
                    return treeNode;
                };
                // 设置树的根节点
                cfg.owner.panelWest.setRootNode(createTreeNode(rootNode));
            }
        });

解析对应XML为

<?xml version="1.0" encoding="UTF-8"?>
<node text="aaa">
    <node text="aaa1" href="index.jsp" hrefTarget="iframe_center"/>
    <node text="aaa2">
        <node text="aaa21" href="bbb21" hrefTarget="iframe_center"/>
        <node text="aaa22" href="bbb22" hrefTarget="iframe_center"/>
    </node>
    <node text="aaa3" href="bbb3" hrefTarget="iframe_center"/>
</node>

节点属性为任何合法的Ext.tree.TreeNode构造属性。
