Xml 使用PL/SQL解析SOAP响应
我试图使用以下代码解析SOAP响应,但得到的是空响应。响应包含多个名称空间,我认为这就是问题所在。有人能指出我做错了什么吗Xml 使用PL/SQL解析SOAP响应,xml,oracle,soap,plsql,Xml,Oracle,Soap,Plsql,我试图使用以下代码解析SOAP响应,但得到的是空响应。响应包含多个名称空间,我认为这就是问题所在。有人能指出我做错了什么吗 declare l_xml xmltype; begin l_xml := xmltype.createXML('<?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/

我也有同样的问题。我发现问题出在前缀名称空间中,比如Oracle XMLType以及如何解释它们。根据您的示例,我解决了提取没有前缀名称空间的内部节点的问题
declare
l_xml xmltype;
begin
l_xml := xmltype.createXML('<?xml version="1.0" encoding="UTF-8"?>

--Pay attention here and changes in path parameter at XMLTABLE
l_xml := l_xml.EXtract('//*/*//return');
for i in (select t.key, t.value
from dual d,
XMLTABLE('/return/item' PASSING l_xml COLUMNS key

您没有在XPath中使用getDataResponse的名称空间作为前缀,也没有包括信封和正文标记;因此,将XPath更改为:
'/SOAP-ENV:Envelope/SOAP-ENV:Body/ns1:getDataResponse/return/item'
仅通过这些更改,您的代码就会生成:
Key is: status
Key is: content
PL/SQL procedure successfully completed.
谢谢Alex,我根据你的建议完成了这项工作。谢谢你给我的提示Seyran,我会在下次使用这个技巧。这看起来有点像黑客,如果你需要来自多个返回节点或一个节点内多个层的数据,尤其是如果有任何节点有名称空间的话,这项工作就不会真正起作用。如果这样做,xmlnamespaces子句是多余的,因为提取的节点没有名称空间前缀。@Alex Poole它有指向名称空间类型ex的链接。如果省略xmlnamespace,您将得到一个错误。我在删除xmlnamespaces子句的情况下运行了您的代码,它工作正常。名称空间位于本例中未被引用的属性上,因此我猜它未被选中?抱歉,同意@Alex Poole。
