出現好多紅色提醒，這些事什么意思
我按照老師說的去打，為什么會出現下面這么多錯誤
com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: 1 字節的 UTF-8 序列的字節 1 無效。

先嘗試一下用eclipse內部的editor打開xml文件，這樣第一個錯誤能解決了，或者將xml中的utf-8改為utf8，但是中文解析時候可能亂碼
二一個是導入的包是否正確
所用到的包有如下幾個
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;
import org.w3c.dom.NamedNodeMap;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;

親，你可能使導錯包了，同名的包很多，要求是org下的或者是JDOMorDOM4J下的包
