Plsql ORA-19202:XML处理中出错ORA-24333:迭代计数为零

我在执行以下过程时遇到以下错误。请帮我找到解决办法。我对在Oracle中使用XML非常陌生。非常感谢你的帮助

我得到的错误是

ORA-19202:XML处理中发生错误 ORA-24333：零迭代计数 ORA-06512:at SYS.DBMS_XMLGEN，第7行 ORA-06512:SYS.DBMS_XMLGEN，第147行 ORA-06512：第69行 1920200000-XML处理%s时出错 *原因：处理XML函数时出错

请给我建议一些解决办法

提前感谢

我认为您使用了错误的功能。看，它需要一个ctxHandle或一个sql。看一看，我注意到你的XML中有一堆谎言被注释掉了。试着删除这些注释掉的行，看看你是怎么做的。
