Jmeter Regular Expression Extractor在xml中找到ItemID

I am new to jmeter; I hope that I can describe my problem to you well enough.

我是jmeter的新手;我希望我能够很好地向你描述我的问题。

I am trying to use regex to extract an ItemID attribute from an xml element. Which I then use in another request. This is the XML response I am trying to extract the ItemID from:

我试图使用正则表达式从xml元素中提取ItemID属性。然后我在另一个请求中使用它。这是我试图从中提取ItemID的XML响应:

<?xml version="1.0" encoding="UTF-8"?>
<Promise >
 <SuggestedOption>
      <Option TotalShipments="1">
           <PromiseLines TotalNumberOfRecords="1">
                <PromiseLine ItemID="Col_001" >
                     <Assignments>
                          <Assignment InteractionNo="1" >
                          </Assignment>
                     </Assignments>
                </PromiseLine>
           </PromiseLines>
     </Option>
 </SuggestedOption>
</Promise>

I have the Regular Expression Extractor set up as follows:

我有正则表达式提取器设置如下:

Reference Name: item
Regular Expression: .?ItemID=(.+?)*
Template: $1$
Match No.: 1

In the 2nd request I have set the ItemID as follows ... ItemID=${item} ...

在第二个请求中,我将ItemID设置如下... ItemID = $ {item} ...

I know that When I use the Default Value set to "Col_001" it works fine. So there is obviously a problem with my Expression.

我知道当我使用设置为“Col_001”的默认值时,它可以正常工作。所以我的表情显然有问题。
