Size limit to javascript [node].nodeValue field?

Question

I\'m receiving XML data via an AJAX call. One of the tags has a large amount of text, roughly 4000-5000 characters. In Firefox, the field is being truncated around the 3000t

@Kooilnc has it right, 4k limit on text nodes in Firefox.

You can work around it by doing this:

function getNodeText(xmlNode) {
    if(!xmlNode) return '';
    if(typeof(xmlNode.textContent) != "undefined") return xmlNode.textContent;
    return xmlNode.firstChild.nodeValue;
}

text = getNodeText(document.getElementsByTagName("div").item(0));
alert(text.length);
