I have a xml file like, <step_list Number=\"5\"> <step Program=\"P1\" Step=\"STEP01\" Seq=\"1\">

相关专题：jquery xml

I have a xml file like,

<step_list Number="5">
    <step Program="P1" Step="STEP01" Seq="1">
    </step>
    <step Program="P2" Step="STEP02" Seq="3">
    </step>
    <step Program="P3" Step="STEP03" Seq="2">
    </step>
    <step Program="P4" Step="STEP04" Seq="5"开发者_JAVA百科>
    </step>
    <step Program="P5" Step="STEP05" Seq="4">
    </step>
</step_list>

I want a way to read this file with ascending order of seq number. Can you give a clue about how is that possible in jQuery ?

    var oxml = $.string2xml(sxml);

    for(var ind = 1; ind < 11; ind++)
    {
        var step = $(oxml).find("step[Seq='"+ind+"']");
        if (step.length > 0)
            $("#resultado").append("<div>"+$(step).attr("Seq")+"</div>");
    }

});

</script>
</head>
<body>
<div id="resultado"></div>

var seq = new Array();

$(xml).find('step_list').each( function() {

} );

So you have an array :)
