只要取出：http://www.youerw.com /coursedown/2012/654/mengd/49921/xmlpath/mengd1338860138788.xml
String str = "你的字符串";
Java code
Matcher matcher = Pattern.compile("<param\\p{Space}+name\\p{Space}*=\\p{Space}*\"LoadDataURL\"\\p{Space}+value\\p{Space}*=\\p{Space}*\"(.*?)\"").matcher(str);
while(matcher.find())
System.out.println(matcher.group(1));
如果是解析本地html文件 ，可以这样
Java code
public static void main(String[] args)throws Exception {
File file = new File("C:\\Documents and Settings\\zhoufeng\\桌面\\aaa.html");
BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file)));
String line = null;
StringBuilder sb = new StringBuilder();
while((line = br.readLine()) != null){
sb.append(line + "\r\n");
}
System.out.println(sb);
Matcher matcher = Pattern.compile("<param\\p{Space}+name\\p{Space}*=\\p{Space}*\"LoadDataURL\"\\p{Space}+value\\p{Space}*=\\p{Space}*\"(.*?)\"").matcher(sb.toString());
while(matcher.find())
System.out.println(matcher.group(1));
}
have a try
Java codeString s = ...; //LZ的字符串
Matcher m = Pattern.compile("(?is).*?<param name=\"LoadDataURL\" value=\"(.*?)\".*");
while (m.find()) {
System.out.println(m.group(1));
}
