在xml(Oracle)中使用名称空间时如何通过xmltable解析xml
我想解析一个xml字符串,它是servier发送的web服务响应,xml如下所示:在xml(Oracle)中使用名称空间时如何通过xmltable解析xml,xml,oracle,plsql,Xml,Oracle,Plsql,我想解析一个xml字符串,它是servier发送的web服务响应,xml如下所示: declare v_xml clob; begin v_xml := '<?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/200
declare
v_xml clob;
begin
v_xml := '<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<addResponse xmlns="http://tempuri.org/">
<addResult>20</addResult>
</addResponse>
</soap:Body>
</soap:Envelope>';
for c in (select results
from xmltable(xmlnamespaces(default 'http://tempuri.org/',
'http://schemas.xmlsoap.org/soap/envelope/' as
"soap" ),
'soap:Envelope/soap:Body/addResponse' passing
xmltype(v_xml) columns results varchar(100) path
'./addResult')) loop
dbms_output.put_line('the result of calculation is : ' || c.results);
end loop;
end;
我想得到元素之间的值20 addResult。我的plsql代码段如下所示:
declare
v_xml clob;
begin
v_xml := '<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<addResponse xmlns="http://tempuri.org/">
<addResult>20</addResult>
</addResponse>
</soap:Body>
</soap:Envelope>';
for c in (select results
from xmltable('Envelope/Body/addResponse' passing xmltype(v_xml)
columns results varchar(100) path './addResult')
)
loop
dbms_output.put_line('the result of calculation is : ' || c.results);
end loop;
end;
似乎没有打印出任何内容,但是如果我删除名称空间“soap”,代码运行良好,那么有人能告诉我,当xml有名称空间时,如何获得值20吗
基于
应该是这样的:
declare
v_xml clob;
begin
v_xml := '<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<addResponse xmlns="http://tempuri.org/">
<addResult>20</addResult>
</addResponse>
</soap:Body>
</soap:Envelope>';
for c in (select results
from xmltable(xmlnamespaces(default 'http://tempuri.org/',
'http://schemas.xmlsoap.org/soap/envelope/' as
"soap" ),
'soap:Envelope/soap:Body/addResponse' passing
xmltype(v_xml) columns results varchar(100) path
'./addResult')) loop
dbms_output.put_line('the result of calculation is : ' || c.results);
end loop;
end;
