您可以使用 XMLTable
以使用XQuery生成路径列表.
You can use XMLTable
to produce list of paths with XQuery.
例如
( SQLFiddle )
with params as (
select
xmltype('
<ALFA>
<BETA>0123</BETA>
<GAMMA>2345</GAMMA>
<DELTA>
<EPSILON>3</EPSILON>
</DELTA>
</ALFA>
') p_xml
from dual
)
select
path_name || '/text()'
from
XMLTable(
'
for $i in $doc/descendant-or-self::*
return <element_path> {$i/string-join(ancestor-or-self::*/name(.), ''/'')} </element_path>
'
passing (select p_xml from params) as "doc"
columns path_name varchar2(4000) path '//element_path'
)
但这是一种错误的方式,至少是因为它没有达到预期的效果.
but it's a wrong way at least because it's not effective as it can.
只需使用相同的XQuery提取所有值: ( SQLFiddle )
Just extract all values with same XQuery: (SQLFiddle)
with params as (
select
xmltype('
<ALFA>
<BETA>0123</BETA>
<GAMMA>2345</GAMMA>
<DELTA>
<EPSILON>3</EPSILON>
</DELTA>
</ALFA>
') p_xml
from dual
)
select
element_path, element_text
from
XMLTable(
'
for $i in $doc/descendant-or-self::*
return <element>
<element_path> {$i/string-join(ancestor-or-self::*/name(.), ''/'')} </element_path>
<element_content> {$i/text()}</element_content>
</element>
'
passing (select p_xml from params) as "doc"
columns
element_path varchar2(4000) path '//element_path',
element_text varchar2(4000) path '//element_content'
)
