带有冒号的Xpath/Xquery

我想用xquery获取一些信息。但是，XML元素有一个冒号的名称带有冒号的Xpath/Xquery

我知道问题必须做一些与名称空间，但因为我正在使用一个简单的xquery intepreter我不知道如何。

这是我非常的做法，但与

let $e := doc('C:\Users\Katharina\workspace\BPMN\process_1.bpmn') 
(: for $k in $e//*[name()='bpmn2:task']:) 
for $k in $e 
return $k

但我没有得到与改变的代码什么..

只是声明命名空间您的XQuery代码中的URI。

declare namespace bpmn2="http://www.omg.org/spec/BPMN/20100524/MODEL"; 

let $e := doc('C:\Users\Katharina\workspace\BPMN\process_1.bpmn') 

for $k in $e//bpmn2:task 
    return $k

谢谢你..我想太多的困难 –

还要注意：）的参数文档（应该是一个URI，而不是一个文件名。某些软件准备接受标准需要URI的文件名，但其他软件则不适用。正确的URI将是'file：/// C：/ Users/Katharina/workspace/BPMN/process_1.bpmn' –
