Question

彩色(Node)方法似乎是一种 b。当我称之为这一方法时,我收到了一部“NAMESPACE_ERR”的DOMException鞭".。

我的法典如下:

DocumentBuilder builder= DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = builder.newDocument();
Node n1 = doc.createElement("node");
Node n2 = n1.cloneNode(true);

任何想法? 事先感谢你!

EDIT : Important note : this code works perfectly if I run it on my computer with the Java JRE. It only fails on Android (1.6 and 2.2)

EDIT2 :并在Andrid 3.1 开展工作。但我需要使用2.2版。是否有工作?

Ok, I found a related bug : http://code.google.com/p/android/issues/detail?id=2735

but now I need a workaround... any idea ? NB : i don t want to add namespace to the created nodes.

I tried this code and seems to work fine. I got the following in the Log

11-17 16:51:54.942: I/(15474): org.apache.harmony.xml.dom.ElementImpl@41413f88
11-17 16:51:54.942: I/(15474): org.apache.harmony.xml.dom.ElementImpl@41414040

Code

button1.setOnClickListener(new OnClickListener(){

@Override
public void onClick(View v) {
    javax.xml.parsers.DocumentBuilder builder = null;
    try {
        builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
    } catch (ParserConfigurationException e) {
        Log.e("","exception,e");
    }
    Document doc = ((javax.xml.parsers.DocumentBuilder) builder).newDocument();
    Node n1 = doc.createElement("node");
    Node n2 = n1.cloneNode(true);
        Log.i("",n1.toString());
        Log.i("",n2.toString());

}
});
