示例XML:
<rss version="2.0">
<channel>
<title>The Channel Title Goes Here</title>
<description>
The explanation of how the items are related goes here
</description>
<link>/events</link>
<item>
<title>
<![CDATA[ some title ]]>
</title>
<description>
<![CDATA[ ]]>
</description>
<content:encoded xmlns:content="http://stuff.com">
<![CDATA[
<event>
<name>some name</name>
<startdate>some date</startdate>
<starttime>some time</starttime>
<location>some place</location>
<description></description>
</event>
]]>
</content:encoded>
</item>
<item>
</item>
...
</channel>
</rss>
我的SAX解析器startElement
方法永远不会进入以下if
语句,但sysout会将“event”打印到logcat。为什么它永远不会发现localName.equals("event")
是true
?
@Override
public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException
{
System.out.println(localName);
if (localName.equals("event")) // <-- never goes in here
{
// do stuff
}
}
是否与CDATA有关,以及我如何设置解析器?以下是我实例化所有内容的方法:
URL sourceUrl = new URL(kEventsURL);
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
MyXMLHandler myXMLHandler = new MyXMLHandler();
xr.setContentHandler(myXMLHandler);
xr.parse(new InputSource(sourceUrl.openStream()));

阅读第一个回答here,了解为什么它无法识别标签启动。您应该运行另一个包含来自element的文本的解析器。

尝试“qName”
而不是“localName”
