获取XML文件中内容大小

即去掉XML中所有<>及包含的内容

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.io.SAXReader;


public class congTools {
	static Document doc;
	static String content;
	
	public congTools(String filename){
		SAXReader reader = new SAXReader();
		try {
			doc = reader.read(filename);
		} catch (DocumentException e) {
			e.printStackTrace();
		}
		content=doc.getRootElement().asXML();
	}
	
	public int getLength(String content){
		String result="";
		String[] results=content.split("<.*?>");
		for(String a:results){
			result+=a;
		}
		return result.length();
	}

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		congTools cl=new congTools("src/00000000000052735781.xml");
		int len=cl.getLength(cl.content);
		System.out.println(len);
	}

}

  

split("<.*?>")表示,按以<开头,以>结尾的字符串作为分隔符
