oracle查詢使用oracle獲取xml節點及其值的列表

-1

我有一個XML列，我需要幫助來編寫查詢以顯示節點及其值。下面oracle查詢使用oracle獲取xml節點及其值的列表

是從我的XML列中的數據：

<item_content> 
    <stimulus_reference> 
    <table_wrapper> 
     <table frame="all" colsep="1" rowsep="1" pgwide="0"> 
     <tgroup cols="3"> 
      <thead> 
      <row> 
       <entry /> 
       <entry align="center">Male</entry> 
       <entry align="center">Female</entry> 
      </row> 
      </thead> 
      <tbody> 
      <row> 
       <entry align="left">Juniors</entry> 
       <entry align="right">12</entry> 
       <entry align="right">3</entry> 
      </row> 
      <row> 
       <entry align="left">Seniors</entry> 
       <entry align="right">9</entry> 
       <entry align="right">21</entry> 
      </row> 
      </tbody> 
     </tgroup> 
     </table> 
    </table_wrapper> 
    <rationale>This is a rationale paragraph</rationale> 
    </stimulus_reference> 
    <task> 
    <item_stem> 
     <stem_paragraph>The table above shows the distribution of students that attended a concert, by class and gender.</stem_paragraph> 
    </item_stem> 
    <item_response> 
     <response_choices> 
     <columnar_choice_list> 
      <columns align="character" align_character="1"> 
      <choice_row numeric_identifier="1"> 
       CHROW1 
       <choice_cell>3</choice_cell> 
      </choice_row> 
      <choice_row numeric_identifier="2"> 
       CHROW2 
       <choice_cell>15</choice_cell> 
      </choice_row> 
      <choice_row numeric_identifier="3"> 
       CHROW3 
       <choice_cell>2102</choice_cell> 
      </choice_row> 
      <choice_row numeric_identifier="4"> 
       CHROW4 
       <choice_cell>321</choice_cell> 
      </choice_row> 
      ColumnsData 
      </columns> 
     </columnar_choice_list> 
     </response_choices> 
    </item_response> 
    </task> 
    <math_expression>1+2=3</math_expression> 
</item_content>

我想在下面的格式

Node_Name    Node_val 

stimulus_reference 
table_wrapper 
table 
tgroup 
thead 
row 
entry 
entry     Male 
entry     Female 
tbody 
row 
entry     Juniors 
entry     12 
entry     3 
row 
entry     Seniors 
entry     9 
entry     21 
task 
item_stem 
stem_paragraph    The table above shows the distribution of students that attended a concert, by class and gender. 
item_response 
response_choices 
columnar_choice_list 
columns     ColumnsData 
choice_row    CHROW1 
choice_cell    3 
choice_row    CHROW2 
choice_cell    15 
choice_row    CHROW3 
choice_cell    2102 
choice_row    CHROW4 
choice_cell    321

輸出非常感謝您對這個幫助。

//*返回所有級別上的所有節點。
name()返回節點名稱
text()返回節點值

如果你只想文本節點上，您有//*[text()]
