XML Files : read by tag

I am using html5 Canvas output and createJS.

This is the XML i am trying to read

<Tour>
<Day Seq="1">

<man1>name1</man1>

<man2>name2</man2>

<man3>name3</man3>

</Day>

<Day Seq="2">

<man1>name1</man1>

<man2>name2</man2>

</Day>

<Day Seq="3">

<man1>name1</man1>

<man2>name2</man2>

<man3>name3</man3>

<man4>name4</man4>

</Day>

<Tour>

My code is :

var reqCurrent = new XMLHttpRequest();
reqCurrent.open("GET", "xxx.xml", true);

reqCurrent.addEventListener("load", fLoader);
reqCurrent.send();

function fLoader(e) {
parserM = new DOMParser();
xmlDocM = parserM.parseFromString(e.target.response, "text/xml");

}

I can read, i mean the code is ok.

Now my problem is to read this file even if number of day will increase with a random number of man.

can someone help me?

Thanks in advance.
