现有如上XML文档，请使用DOM为id为1的汽车添加长度元素(length)，同时修改fixed元素的值为30，并将id为2的汽车fixed元素删除。

以上代码中，需要导入jar包：xerces-2.6.2.jar，由于之前导入的是xerces-2.3.0.jar包，遇到`java.lang.AbstractMethodError: org.apache.crimson.tree.XmlDocument.getXmlStandalone()Z`报错，换成xerces-2.6.2.jar就可以了！

原先还有导入crimson.jar包，但也是报这个错误，后来查到是sun把crimson.jar给废了，可是又没有错误提示。把crimson.jar删除了，xml就可以正常生成了。

在控制台和源文件car.xml输出如下：
