存在名称空间时更新XML

我必须更新XML中的值：

<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet" 
                  xmlns:o="urn:schemas-microsoft-com:office:office" 
                  xmlns:x="urn:schemas-microsoft-com:office:excel" 
                  xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet" 
                  xmlns:html="http://www.w3.org/TR/REC-html40">
            <DocumentProperties xmlns="urn:schemas-microsoft-com:office:office">
                <Author>XXXXXX</Author>
                <LastAuthor>UCB User</LastAuthor>
                <Created>2019-10-31T13:04:09Z</Created>
                <Version>14.00</Version>
            </DocumentProperties>
            <a>5</a>
        </Workbook>

//.getClobVal（）最终是因为ORA-21500:内部错误代码，参数：[%s]，%s]，%s]，%s]，%s]，%s]，%s]（）

上面的代码不会改变任何东西。我认为这是因为DocumentProperties标记中声明了另一个名称空间。但我不知道如何在子句中声明名称空间

当我尝试使用此代码更新/Workbook/a中的值时，它可以正常工作：

select UPDATEXML(xml_val,
   '/Workbook/a/text()',2020-01-08,
    'xmlns="urn:schemas-microsoft-com:office:spreadsheet" 
              xmlns:o="urn:schemas-microsoft-com:office:office" 
              xmlns:x="urn:schemas-microsoft-com:office:excel" 
              xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet" 
              xmlns:html="http://www.w3.org/TR/REC-html40"').getClobVal() as last
from tt;

我尝试过但不起作用的不同名称空间组合：

--一,

--二,

--三,

--四,

---

注意：我无法删除DocumentProperties标记中的名称空间声明，因为此XML是format file的一部分，

DocumentProperties

元素及其子元素位于名称空间

urn:schemas microsoft com:office:office

，它具有快捷方式

o

；您需要在Xpath中为这些元素添加名称空间前缀：

选择UPDATEXML(
xml_val，
“/工作簿/o:DocumentProperties/o:Created/text（）”，
'2020-01-08',
'xmlns=“urn:schemas microsoft com:office:spreadsheet”
xmlns:o=“urn:schemas microsoft com:office:office”
xmlns:x=“urn:schemas microsoft com:office:excel”
xmlns:ss=“urn:schemas microsoft com:office:spreadsheet”
xmlns:html=”http://www.w3.org/TR/REC-html40"'
)作为更新的xml
来自tt；
