如何在空手道的 XML 响应中获取标签计数和标签值列表

问题描述

我的回复如下

    <List>
     <Fee>
      <Amount>10</Amount>
     </Fee>
     <Fee>
      <Amount>10</Amount>
      <Amount>20</Amount>
     </Fee>
    </List>

我想获得每笔费用的金额标签计数.还有每项费用的金额列表.

I would like to get count of Amount tag for each fee. Also list of amounts for each fees.

如何在空手道中实现这一目标.

How to achieve this in karate.

fee1 1 金额标签Fee2 2 个金额标签

fee1 1 amount tagsFee2 2 amount tags

推荐答案

* def response =
"""
<List>
  <Fee>
    <Amount>10</Amount>
  </Fee>
  <Fee>
    <Amount>10</Amount>
    <Amount>20</Amount>
  </Fee>
</List>
"""

您可以像这样使用 XPath 获取所有第二个数量的数组:

You can get an array of all the second amounts using XPath like this:

* def amt2 = /List/Fee[2]/Amount
* match karate.sizeOf(amt2) == 2

但在空手道中，返回单个节点的 XPath 将不是数组.但是你可以使用一些条件逻辑:

But in Karate, an XPath that returns a single node will not be an array. But you can use some conditional logic:

* def amt1 = /List/Fee[1]/Amount
* if (karate.typeOf(amt1) != 'list') amt1 = ([amt1])
* match karate.sizeOf(amt1) == 1

以下是编写辅助函数的方法:

Here is how you can write a helper function:

* def fun = function(index){ var temp = karate.xmlPath(response, '/List/Fee[' + index + ']/Amount'); return karate.typeOf(temp) == 'list' ? temp : [temp] }
* match fun(1) == ['10']
* match fun(2) == ['10', '20']

如果上面有任何不清楚的地方，请阅读文档.

And please read the docs if any of the above is not clear.
