XmlResourceParser.getText()返回null [英] XmlResourceParser.getText() returning null

问题描述

我有一个名为xml的XmlResourceParser实例.如我的代码所示，当我尝试在节点上调用getText()时，它返回null.这很奇怪，因为我可以在返回正确值的同一节点上调用getName()，因此实例已正确设置.这是我的代码:

I have an XmlResourceParser instance called xml. When I try to call getText() on a node, as seen in my code, it returns null. This is strange because I can call getName() on the same node it returns the proper value, so the instance is set up properly. Here is my code:

    XmlResourceParser xml = context.getResources().getXml(R.xml.thesaurus);

    try {
        //if (xml.getName().equals("word")) {
            xml.next(); //to the first node within <word></word>
            boolean notFound = true;
            while (notFound) {
                xml.next();
                if (xml.getName() != null && xml.getName().equalsIgnoreCase("synonyms")) {
                    String synonym = xml.getText();
                    Log.v(TAG, String.valueOf(synonym));
                    notFound = false; //found
                }
            }
        }
    } catch (XmlPullParserException xppe) {
        xppe.printStackTrace();
    } catch (IOException ioe) {
        ioe.printStackTrace();
    }

这是我的XML，即使它没有任何问题:

Here is my XML, even though there isn't anything wrong with it:

<?xml version="1.0"?>
<thesaurus>
    <word name="let">
        <synonyms>allow</synonyms>
    </word>
</thesaurus>

任何帮助将不胜感激！谢谢！

我找到了自己的答案在这里.我使用了@Libin在此答案中发布的代码.

I found my own answer here. I used the code posted in this answer by @Libin.

    int eventType = xmlResourceParser.getEventType();
    while (eventType != XmlPullParser.END_DOCUMENT) {
        if (eventType == XmlPullParser.START_DOCUMENT) {
            System.out.println("Start document");
        } else if (eventType == XmlPullParser.START_TAG) {
            System.out.println("Start tag " + xmlResourceParser.getName());
        } else if (eventType == XmlPullParser.END_TAG) {
            System.out.println("End tag " + xmlResourceParser.getName());
        } else if (eventType == XmlPullParser.TEXT) {
            System.out.println("Text " + xmlResourceParser.getText());
        }
        eventType = xmlResourceParser.next();
    }
