Question

我有这个查询工作多年，直到最近我在收集器中更改了另一个查询并保存。我根本没有改变这个xml查询，但现在它在xml部分失败了。我绝对不会精通xml，所以我正在寻找一些帮助来查看问题所在。这是我收到的错误消息：

ORA-31011：XML解析失败ORA-19202：XML中发生错误处理LPX-00210：预期＆＃39;＆lt;＆＃39;而不是＆＃39; M＆＃39;第1行出错 ORA-06512：at＆＃34; SYS.XMLTYPE＆＃34;，第0行ORA-06512：第1行

这是我的查询工作正常，现在不是：

Answer 1

您的PLPROD_MORT.MENU表的MENUDATA列中包含数据，其中包含字符串值（本例中为CLOB），这些数据不是有效的XML。从您得到的错误中，您至少有一个以M开头的值，但您在评论中的测试表明您有31行具有非XML值。

我推测值可能是文字字符串'MENUDATA'，因为它会得到同样的错误：

select xmltype('MENUDATA') from dual;

Error starting at line : 1 in command -
select xmltype('MENUDATA') from dual
Error report -
SQL Error: ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00210: expected '<' instead of 'M'
Error at line 1
ORA-06512: at "SYS.XMLTYPE", line 310
ORA-06512: at line 1
31011. 00000 -  "XML parsing failed"
*Cause:    XML parser returned an error while trying to parse the document.
*Action:   Check if the document to be parsed is valid.

但它只是告诉你它以M开头。但是，如果它确实具有该字面值，我会进一步推测某人插入或更新了数据并意外地使用了文字而不是标识符，例如使用以下方法复制现有条目：

insert into PLPROD_MORT.MENU(MENUDATA) 
select 'MENUDATA' from PLPROD_MORT
where ...

而不是：

insert into PLPROD_MORT.MENU(MENUDATA) 
select "MENUDATA" from PLPROD_MORT
where ...

但这是几层推测，无论是什么导致原始数据问题都与您询问的查询无关 - 这只是看到了不良数据的症状。

Answer 2

Oracle抱怨“SYS.XMLTYPE”不是有效的xml列或类型。它期望<element>....</element>格式

Answer 3

我遇到了同样的问题，我可以通过纠正extractvalue()函数中的Xpath来解决这个问题。我为CLOB值提取输入了错误的Xpath。希望这可能有助于解决您的问题。
