我有这个XML文件:
<description>
<![CDATA[
<tag1 hello world/><br/>
<b>Current Conditions:</b>
]]>
</description>
我需要提取tag1
,br
和b
。这是我的代码:
NodeList nl = eElement.getElementsByTagName("description");
for (int j = 0; j < nl.getLength(); j++) {
Node n = nl.item(j);
Element e = (Element)n;
String s = getElement(e));
}
public static String getElement(Element e) {
NodeList list = e.getChildNodes();
String data;
for(int index = 0; index < list.getLength(); index++){
if(list.item(index) instanceof CharacterData){
CharacterData child = (CharacterData) list.item(index);
data = child.getData();
if(data != null && data.trim().length() > 0)
return child.getData();
}
}
return "";
}
输出是:
<tag1 hello world/><br/>
<b>Current Conditions:</b>
但我需要String [] str
以下值:
str[0] = "hello world";
str[1] = "";
str[3] = "Current Condition:";
答案 0 :(得分:2)
CDATA块的目的是将内容保存为未解析的字符数据(这是您所看到的)。获得String
后,您可以对其进行解析以访问其数据。
