Question

我正在尝试修复我编写的将srt文件转换为dxfp.xml的代码中的错误。它工作正常但是当有一个特殊字符如＆符号时会抛出java.lang.NumberFormatException错误。我尝试使用apache commons中的StringEscapeUtils函数来解决它。有人可以向我解释一下我在这里失踪了吗？提前谢谢！

        converter.writeXML(dfxp);
        System.out.println("Conversion Complete");
    }
}

这是srt文件的一部分，它在导出并作为jar文件运行时抛出错误。
