XPath出錯。節點不能用於創建它的文檔以外的其他文檔

我想用XPath解析xml文檔。XPath出錯。節點不能用於創建它的文檔以外的其他文檔

該腳本適用於Chrome瀏覽器就好了，但給我下面的錯誤：

WrongDocumentError: Node cannot be used in a document other than the one in which it was created

有問題的代碼如下：

function StringToXML(oString) { 
    //code for IE 
    if (window.ActiveXObject) { 
     var oXML = new ActiveXObject("Microsoft.XMLDOM"); oXML.loadXML(oString); 
     return oXML; 
    } 
    // code for Chrome, Safari, Firefox, Opera, etc. 
    else { 
     return (new DOMParser()).parseFromString(oString, "text/xml"); 
    } 
} 

function parseGpx(xmlText){ 
    var pointArray = new Array(); 
    var $xml = StringToXML(xmlText); 
    var path = "//*[local-name()='trkpt']"; 
    var paragraphCount = document.evaluate(path, $xml, null, XPathResult.ORDERED_NODE_ITERATOR_TYPE, null); 
    //this last line is what is causing the problems.

我想知道什麼可能是這個問題，這是我的console.logs結果：

我很奇怪，爲什麼會發生這種事，幾乎所有的谷歌搜索結果這個問題是TinyMCE的關係，而不是非常有幫助。

取而代之的是：

var paragraphCount = document.evaluate(path, $xml, null, 
         XPathResult.ORDERED_NODE_ITERATOR_TYPE, null);

你應該使用：

var paragraphCount = $xml.evaluate(path, $xml, null, 
         XPathResult.ORDERED_NODE_ITERATOR_TYPE, null);
