无法检索嵌套在另一个标签内容内的XML标签
|
谢谢阅读！
使用此处的XML解析教程作为参考，我试图解析具有以下结构的简单XML RSS feed。
除以下情况外，一切工作正常，所有值均已解析：我无法获取
<img>
<feed>
<title>This is Title</title>
<count>10</count>
<desc>
This is a description for a sample feed <img src=\"http://someimagelink.com/img.jpg\" />
</desc>
<link>This is link</link>
</feed>
endElement()
@Override
public void endElement(String uri, String localName, String qName)
throws SAXException {
if(localName.equals(\"feed\")) {
//Add Records object to ArrayList
//Feed is a POJO class to store all the feed content.
//FeedList is an ArrayList to store multiple Feed objects.
mFeedList.add(mFeed);
}
else if(localName.equals(\"title\")) {
mFeed.setTitle(currentValue.toString());
}
else if(localName.equals(\"count\")) {
mFeed.setCount(currentValue.toString());
}
else if(localName.equals(\"desc\")) {
mFeed.setDesc(currentValue.toString());
}
else if(localName.equals(\"img\")) {
//NEVER hits here :(
mFeed.setImageUrl(currentValue.toString());
}
else if(localName.equals(\"link\")) {
//BUT, hits here
mFeed.setLink(currentValue.toString());
}
<img>
<desc>
<desc>
String
<img>
<img>
startElement()
startElement()
@Override
public void startElement(String uri, String localName, String qName,
Attributes attributes) throws SAXException {
if(localName.equals(\"feed\")) {
//Instantiate Feed object
mFeed = new Feed();
}
else if(localName.equals(\"title\")) {
currentValue = new StringBuffer(\"\");
isBuffering = true;
}
else if(localName.equals(\"count\")) {
currentValue = new StringBuffer(\"\");
isBuffering = true;
}
else if(localName.equals(\"desc\")) {
currentValue = new StringBuffer(\"\");
isBuffering = true;
}
else if(localName.equals(\"img\")) {
currentValue = new StringBuffer(\"\");
isBuffering = true;
}
}
else if(localName.equals(\"link\")) {
currentValue = new StringBuffer(\"\");
isBuffering = true;
}
}

标记实际上没有字符内容，必须将您想要的值从属性中拉出。 为此，您需要覆盖，在执行操作时或多或少地识别标记，并从参数中获取所需的值。 调试帮助： 使用此（简单/愚蠢）处理程序：package com.donroby.so; import org.xml.sax.Attributes; import org.xml.sax.SAXException; import org.xml.sax.helpers.DefaultHandler; public class DebugHandler extends DefaultHandler { @Override public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException { printParseInfo(\"startElement:\", uri, localName, qName); int attributesLength = attributes.getLength(); for (int i = 0; i < attributesLength; i++) { printAttributeInfo(attributes, i); } } @Override public void endElement(String uri, String localName, String qName) throws SAXException { printParseInfo(\"endElement: \", uri, localName, qName); } @Override public void characters(char[] chars, int start, int length) throws SAXException { String str = \"\"; for (int i = start; i < start + length; i++) str += chars[i]; System.out.println(\"Characters: \'\" + str + \"\'\"); } private void printAttributeInfo(Attributes attributes, int i) { System.out.println(String.format(\"%s URI: \'%s\', localName: \'%s\', qName: \'%s\', Value: \'%s\'\", \"Attribute \", attributes.getURI(i), attributes.getLocalName(i), attributes.getQName(i), attributes.getValue(i))); } private void printParseInfo(String type, String uri, String localName, String qName) { System.out.println(String.format(\"%s URI: \'%s\', localName: \'%s\', qName: \'%s\'\", type, uri, localName, qName)); } }
