Jmeter Regular Expression Extractor在xml中找到ItemID

我是 jmeter的新手;我希望我能够很好地向你描述我的问题.

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>

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

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

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.

解决方法

试试这个表达式：

\bItemID\s*=\s*"([^"]*)"
