javascript - jquery 读取 xml block

Question

我读了这个 XML 文件:

<?xml version="1.0" encoding="utf-8" ?>
<parse version="beta" release='1'>
    **<env str="p1" open='config' close='end'/>
    <env str="p2" open='edit' close="next"/>**
    <open str="config system global" jmp="1">
        <set str="set hostname" nomr="hostname"></set>
    </open>
    <open  str="config system interface" jmp='6'>
        <open str="edit" norm="intfisdef" jmp='2'>
            <set str="set ip" norm="intfisip"/>
            <set str="set alias" norm="intnom"/>
            <open str="config secondaryip" jmp='0'>
                <open str="edit" norm="intfisindsecdef" jmp='1'> 
                    <set str="set ip" norm="intfisindsecip"/>
                </open>
            </open>
        </open>
    </open>
 </parse>

有了这个功能:

function alertit2(jqueryObject) {
    jqueryObject.each(function() {
        node = (this);
        str = $(node).attr("str");
        NodeName = node.nodeName;
        console.log("Node Name=" + NodeName + "\nstr=" + str + "\ncmd=" + StringaComando);

        if (NodeName == "open" && StringaComando.substr(0, str.length) == str) {
            FindOpen++;
            alert ("find this");
            return node;
        }
    });
    StringaComando = "";    
}

我调用alertit2什么时候StringaComando有效(“配置系统全局”):，

if (FindOpen==0)
    var Figlio = alertit2($(XML).find('parse').children());
else
    alertit2($(Figlio));

输出是

Node Name=env str=p1 cmd=config system global

Node Name=env str=p2 cmd=config system global

Node Name=open str=config system global cmd=config system global

find this

Node Name=open str=config system interface cmd=config system global

> Node Name=env str=p1 cmd=set access-banner disable

Node Name=env str=p2 cmd=set access-banner disable

Node Name=open str=config system global cmd=set access-banner disable

Node Name=open str=config system interface cmd=set access-banner disable

Node Name=env str=p1 cmd=set admin-concurrent enable

Node Name=env str=p2 cmd=set admin-concurrent enable

Node Name=env str=p1 cmd=set admin-concurrent enable

我的问题:为什么我看到节点:Node *Name=env* str=p1 cmd=set access-banner disable ？

目标是一旦找到“config system global”，就继续解析包含在 block <open str=config system global... 中的开集。

谢谢

当您的条件为 StringaComando 满足。

通过返回 node，您将返回一个 true-ish 值，表示 .each() 循环应该继续；返回 false 表示不应继续下一项。
