我想使用cx_oracle从Oracle表中检索XMLTYPE数据。 数据如下：
<infos>
<Comment/>
<Observation>àéèç</Observation>
<Level>L3</Level>
<Duration/>
<Cause/>
<Depot> Haren </Depot>
<Resolution/>
</infos>
这是我的代码：
#!/usr/bin/python
from __future__ import print_function
import cx_Oracle
# Connection to RTDIAG
try:
dsn_test = cx_Oracle.makedsn(host='xxxxx',port='1521',service_name='xxxxx')
con_test = cx_Oracle.connect(user='xxxx', password='xxxxx',dsn=xxxx)
except cx_Oracle.InterfaceError:
print ("Impossible to connect to the DB!")
print ("***exit script***")
quit()
ID_record = 1729
cursor = con_test.cursor()
query = """select a.content.getClobVal() from emb_log a where ID = :id and uncompleted_record=1
"""
cursor.execute(query,id=1729)
xml_retrieved = cursor.fetchone()[0].read() #string
print (xml_retrieved)
这就是我得到的
<infos>
<Comment/>
<Observation>aeec</Observation>
<Level>L3</Level>
<Duration/>
<Cause/>
<Depot> Haren </Depot>
<Resolution/>
</infos>
不能正确检索XML子级中包含的特殊字符。它们以“ ascii like”字符转换。
为什么以及如何完全按照XML在数据库中显示的方式获取XML？
谢谢。
