copied!<p>There are a couple of issue within the script that would prevent the <code>if</code> statement executing correctly.</p> <ol> <li>The boolean and operator in JavaScript is <code>&&</code> not <code>and</code>. Note the if you use <code>&</code> this would be a bitwise and.</li> <li><p>The tests should not be a string. Due to JavaScript type coersion it a string will be converted to a boolean. A <code>null</code> or empty string <code>''</code> will evaluate <code>false</code>, all other strings will evaluate <code>true</code>. Currently you have</p> <pre><code>if("test1 and test2") </code></pre> <p>This should be</p> <pre><code>if(test1 && test2) </code></pre></li> </ol> <p>So far your updated script would be</p> <pre><code><script> function getSelectedValue() { if(document.getElementById('type').value==1 && document.getElementById('cablegroup5').value==9 && document.getElementById('cablegroup3').value==22 && document.getElementById('cablelength').value == 11) { // Process Xml } } </script> </code></pre> <p>You need to use the browser xml parser to handle your xml. I will assume that you have an xml string, if you have a document object then you will have to change the following slightly, this is from <a href="http://www.w3schools.com/Xml/xml_parser.asp" rel="nofollow">w3schools</a>.</p> <pre><code> var xmlString = "<Products>" + "<Product partnumber='foo'>This is product 1</Product>" + "<Product partnumber='bar'>This is product 2</Product>" + "</Products>"; // Load into an XML document var myDoc; if (window.DOMParser) { var parser=new DOMParser(); myDoc=parser.parseFromString(xmlString,"text/xml"); } else // Internet Explorer { myDoc=new ActiveXObject("Microsoft.XMLDOM"); myDoc.async="false"; myDoc.loadXML(xmlString); } // Get all product nodes var products = myDoc.getElementsByTagName('Product'); var i, targetProduct, partNumber; for(i = 0; i < products.length; i += 1){ // Get the partnumber attribute partnumber = products[i].attributes.getNamedItem('partnumber'); // Ensure that the partnumber exists and its value is what is wanted if(partnumber && partnumber.value == 'foo'){ targetProduct = products[i]; // Exit for break; } } // If the product has been found alert its value. if(targetProduct != null){ alert(targetProduct.textContent || targetProduct.text); } </code></pre> <p>If you were selected a node by id then you could use <code>xmlDoc.getElementById</code> instead of iterating through all nodes of a type and checking attributes.</p> <p>To select the text value of an xml node most browsers use the property <code>textContent</code> although Internet Explorer uses <code>text</code>. The line</p> <pre><code> targetProduct.textContent || targetProduct.text </code></pre> <p>returns <code>textContent</code> if it is present and not null, or the value of <code>text</code>.</p>
