Hello all,
I’m trying to shuffle my Xml doc. What I do is load a xml file into
XmlDocument and have it return a XmlNode object represent my Xml doc.
    XmlNode node = doc.DocumentElement;
The Xml file look like:  
<control id=”ctr1”>
    <action id=”act1”>
    <action id=”act2”>
</control>
<control id=”ctr2”>
    <action id=”act3”>
    <action id=”act4”>
</control>
Then I pass the node returned by the XmlDocument object to
“TestCaseShuffling” method and call it recursively.
The method:
//I’m implementing Fisher-Yates algorithm for the shuffling
private void TestCaseShuffling(XmlNode node, Random rand)
{
    int pCount = node.ChildNodes.Count;

    if(pCount > 1)
    {
        XmlNode temp;//node to swap
        XmlNode temp2;//node to swap
        for(int i = 0; i < pCount; i++)
        {   
            int r = rand.Next(i,pCount);
       
            temp = node.ChildNodes[r].Clone();
            temp2 = node.ChildNodes[i].Clone();

            node.ReplaceChild(temp2,node.ChildNodes[r]);
            node.ReplaceChild(temp,node.ChildNodes[i]);
        }
    }
}

The produced result:
<control id=”ctr2”>
    <action id=”act4”>
    <action id=”act3”>
</control>
<control id=”ctr1”>
    <action id=”act2”>
    <action id=”act1”>
</control>

I’m thinking using XpathNavigator instead of working with XmlNode directly.
Would this be more effective? Or any one have any better idea?
