Question

我需要使用xml技术来解析StaXParser文件。我尝试过，但是无法生成所需的输出。以下是我的文件：

主班

package xml;

public class TestRead {
    public static void main(String args[]) {
        StaXParser2 read = new StaXParser2();
        read.readConfig("C:\\Users\\Google\\Desktop\\kkkk\\Comediah\\Comediah\\Local\\Book2.xml");
    }
}

无输出。只是空白。我对其进行了调试，发现它没有进入块以将布尔标志变为true。

Answer 1

您应该使用element.getName().getLocalPart()而不是element.getName().toString()

getName包含名称空间urn（在这种情况下，getName()会导致类似{urn:schemas-microsoft-com:office:excel}DATA的情况，因此您的equals检查存在缺陷。

无法使用StaXParser解析xml
