我在android中解析一个名为responseText的xml字符串时遇到了一些麻烦.xml完全有效,并具有以下结构:

<plan>
<entry>
<name>john</name>
<address>uk</address>
</entry>
<entry>
<name>joe</name>
<address>usa</address>
</entry>
</plan>

我用来解析String的代码如下:

    try {
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();
        InputSource is = new InputSource();

        is.setCharacterStream(new StringReader(responseText));

        Document doc = db.parse(is);
        NodeList nodes = doc.getElementsByTagName("entry");

        for (int i = 0; i < nodes.getLength(); i++) {

            Element element = (Element) nodes.item(i);

            NodeList name = ((Document) element)
                    .getElementsByTagName("name");
            Element line = (Element) name.item(0);
            Toast.makeText(Containers.this,
                    getCharacterDataFromElement(line), Toast.LENGTH_SHORT)
                    .show();

            NodeList title = ((Document) element)
                    .getElementsByTagName("address");
            line = (Element) title.item(0);
            Toast.makeText(Containers.this,
                    getCharacterDataFromElement(line), Toast.LENGTH_SHORT) …
