Re: Error in XPath expression with IE

I'm solving this by using this piece of sh**, hmm, code

	var nodes=xmlDoc.selectNodes("(//Menu)["+(pos)+"]/MenuTitulo")[0];
	var xpath="";
	var parent="../../"
	while(nodes!=null){
		xpath=">> "+Sarissa.serialize(nodes) + xpath;
		nodes = xmlDoc.selectNodes("(//Menu)["+(pos)+"]/"+parent+"MenuTitulo")[0];
		parent+="../../";
	}

i'm successively adding ../../ to the xpath expression to get the
grand-parent of the Menu i'm in (selected by pos) and getting the
node... That's unbelivable i have to do this like this.

And i still have a problem, it seems some msxml uses a XPath 0 based
and some others 1 based. When pos=1 in some i get 2 values instead of
1!!!

I'm turning this to the Sarissa guys for help, but if someone on this
list can help i'll be extremilly thankful.
