Getting the correct page number

Question

Hi, Im stuck with this project...
I have this xml tag
<page id="p4" type="cyan">some content</page>
so, what I want to do is, use this attributes to apply a B-Cyan, B-Magenta or B-Yellow master spread to
(well to whatever page number there is on the tag) in this case page 4 (and 5 implicitly)
im stuck here
if( !myRoot.xmlAttributes.itemByName("xmlns:xml").isValid )
myRoot.xmlAttributes.add( "xmlns:xml", "http://www.w3.org/XML/1998/namespace" );
if( !myRoot.xmlAttributes.itemByName("xmlns:aid").isValid )
myRoot.xmlAttributes.add( "xmlns:aid", "http://ns.adobe.com/Adobe InDesign/4.0/" );
if( !myRoot.xmlAttributes.itemByName("xmlns:aid5").isValid )
myRoot.xmlAttributes.add( "xmlns:aid", "http://ns.adobe.com/Adobe InDesign/5.0/" );
//**Types of pages
var myPageNode= myRoot.evaluateXPathExpression("//page");
for (var x = 0; x < myPageNode.length; x++){
                    var pageNumber  =  myPageNode[x].xmlAttributes.itemByName("id").value.replace("p","").replace(" ","");
                    var myTypeOfPage = myPageNode[x].xmlAttributes.itemByName("type").value;
                    if (myTypeOfPage = "cyan"){
                         app.activeDocument.pages.itemByName().appliedMaster = app.activeDocument.masterSpreads.item("B-Cyan")
                    if (myTypeOfPage = "magenta"){
                        app.activeDocument.pages.itemByName().appliedMaster = app.activeDocument.masterSpreads.item("B-Magenta")
                    if (myTypeOfPage = "yellow"){
                        app.activeDocument.pages.itemByName().appliedMaster = app.activeDocument.masterSpreads.item("B-Yellow")
i dont know how to pass the correct value to: pages.itemByName( my page tag id number should get here )

Hi schiuma24,
I just modified your JS code, Please try the below code its works fine!
var myDoc = app.activeDocument;
var myRoot = myDoc.xmlElements[0];
var myPageNode= myRoot.evaluateXPathExpression("//page");
for (var x = 0; x < myPageNode.length; x++){
    var pageNumber  =  myPageNode[x].xmlAttributes.itemByName("id").value.replace(/[a-z]/gi, "");
    var myTypeOfPage = myPageNode[x].xmlAttributes.itemByName("type").value;
    if (myTypeOfPage == "cyan"){
        myDoc.pages.item(pageNumber).appliedMaster = myDoc.masterSpreads.item("B-Cyan");
    else if (myTypeOfPage == "magenta"){
        myDoc.pages.item(pageNumber).appliedMaster = myDoc.masterSpreads.item("B-Magenta");
    else if (myTypeOfPage == "yellow"){
        myDoc.pages.item(pageNumber).appliedMaster = myDoc.masterSpreads.item("B-Yellow");
here is your mistake!!
   if (myTypeOfPage = "cyan"){// Here your not compare the the cyan, you assign the value.
thx,
