XML file example:

<?xml version="1.0" encoding="utf-8"?>
<Data>
    <Logo>Logo Test</Logo>
    <Title>Title Test</Title>
    <Subtitle>Subtitle Test</Subtitle>
    <Menu>
        <Item Name="Item 1" DataPath="DP Test" />
        <Item Name="Item 2" DataPath="DP Test" />
        <Item Name="Item 3">
            <Item Name="SubItem 1" DataPath="DP Test" />
            <Item Name="SubItem 2" DataPath="DP Test" />
            <Item Name="SubItem 3" DataPath="DP Test" />
            <Item Name="SubItem 4" DataPath="DP Test" />
            <Item Name="SubItem 5" DataPath="DP Test" />
        </Item>
        <Item Name="Item 4">
            <Item Name="SubItem 1" DataPath="DP Test" />
            <Item Name="SubItem 2" DataPath="DP Test" />
            <Item Name="SubItem 3" DataPath="DP Test" />
        </Item>
        <Item Name="Item 5" Type="T Test" DataPath="DP Test" />
    </Menu>
</Data>

PHP code:

$xmlDoc = new DOMDocument(); // Load a XML file.
$xmlDoc->load("menu.xml");
       
$XMLNode = $xmlDoc->documentElement;

//We go through all nodes from the XML and test their names. Depending on their names we take necessary actions.
foreach ($XMLNode->childNodes as $currentNode){
    if (strtolower($currentNode->nodeName) == "logo"){
        echo $currentNode->nodeValue."<br />"; // Read a node value.
    }
    if (strtolower($currentNode->nodeName) == "title"){
        echo $currentNode->nodeValue."<br />";
    }          
    if (strtolower($currentNode->nodeName) == "subtitle"){
        echo $currentNode->nodeValue."<br />";
    }          
    if (strtolower($currentNode->nodeName) == "menu"){
        foreach ($currentNode->childNodes as $menuItem){
            // Test if node has children.              
            if (strtolower($menuItem->nodeName) == "item" && $menuItem->hasChildNodes()){
                echo $menuItem->getAttribute(‘Name’)."<br />"; // Read a node attribute.
       
                foreach ($menuItem->childNodes as $submenuItem){
                    if (strtolower($submenuItem->nodeName) == "item"){
                        echo $submenuItem->getAttribute("Name");
                        echo $submenuItem->getAttribute("DataPath");
                    }                                  
                }
            }
            elseif (strtolower($menuItem->nodeName) == "item"){
                echo $menuItem->getAttribute("Name");

JavaScript code:

var xmlHttpVariable; // Declare a global variable.

// HTTP request object.
function GetXmlHttpObject(){
    var xmlHttp = null;

    try{
        xmlHttp = new XMLHttpRequest();
    }
    catch (e){
        try{
            xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
        }
        catch (e){
            xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
        }
    }

    return xmlHttp;
}

function callServer(){
    xmlHttpVariable = new GetXmlHttpObject(); // Call HTTP request object.
    var url = "url"; // Set the URL to the server-side script.
    var variables = "var1=val1&amp;var2=val2"; // Set the variables.
    xmlHttpVariable.onreadystatechange = stateChangedVariable; // Call a function on state change.
    xmlHttpVariable.open("POST",url,true); // Open the URL.
    // Send the proper header information along with the request.
    xmlHttpVariable.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    xmlHttpVariable.setRequestHeader("Content-length", variables.length);
    xmlHttpVariable.setRequestHeader("Connection", "close");
    xmlHttpVariable.send(variables); // Send the variables.
}

function stateChangedVariable(){
    if (xmlHttpVariable.readyState == 4){// Values for readyState see below for explanations.
        if (xmlHttpVariable.responseText.replace(/^\s+|\s+$/g, "") == "return value"){
            // Action here.
        }
    }
}

readyState values:

0 – Represents an “uninitialized” state in which an XMLHttt pRequesobject has been created, but not initialized.

1 – Represents a “sent” state in which code has called the XMLHttpRequest open() method and the XMLHttpRequest is ready to send a request to the server.

2 – Represents a “sent” state in which a request has been sent to the server with the send() method, but a response has not yet been received.

3 – Represents a “receiving” state in which the HTTP response headers have been received, but message body has not yet been completely received.

4 – Represents a “loaded” state in which the response has been completely received.
