以上是存储在表列中的XML文件的一部分。我想提取标记<item>和</item>之间的所有字符串。 <item>的单个文件中有多个值。我正在使用oracle 9i。任何人都可以提供适当的查询吗？
答案 0 :(得分：0)
弄清楚XML中XPath的值是什么，然后使用ExtractValue
http://docs.oracle.com/cd/B10501_01/appdev.920/a96620/xdb04cre.htm#1024805
e.g。
select <your_rowid>, extractvalue( xmltype(<your_column>), <your_xpath>) from <your_table>
对于多个值，只需在同一个选择中执行多个提取值。
