使用相同的 XPath 处理多个 XML 元素

Question

我在同一个 XML 中使用同一个 Xpath 修改多个元素时遇到问题。这是代码：

*** Settings ***
Library    XML
Library    String

*** Variables ***
${XMLpath}   AbsolutePath.xml
${Xpath}    GM/BODY/CMss/message  #(there are two elements with this xpath)

*** Test Cases ***
TestCase
    ${root}  Parse Xml  ${XMLpath}
    @{CMmessage}     Get Elements Text   ${root}  ${Xpath}
    
    ${CMmessage1}  Set Variable  @{CMmessage}[1]
       #...CMmessage1 modifications...
    Set  ${root}  ${CMmessage1}  \  ${Xpath} #Here is failing due there are multiple elements (2) matching the XPath
    
    ${CMmessage2}  Set Variable  @{CMmessage}[2]
       #...CMmessage2 modfications...
    Set  ${root}  ${CMmessage1}  \  ${Xpath} #Here is failing due there are multiple elements (2) matching the XPath

    Save Xml  ${root}  ${XMLpath}

有问题，给定的 Xpath 不唯一。我试过索引：

Set ${root} ${CMmessage1} \ ${Xpath}[1] Set ${root} ${CMmessage1} \ ${Xpath}[2]

但这没用...有谁知道如何处理 Robotframework-XMLlibrary 中的索引？

Answer 1

您需要对这些元素进行一些处理。

使用 Get Elements 关键字。

Answer 2

好的，终于找到问题了。使用

Set  ${root}  ${CMmessage1}  \  ${Xpath}[1]

错了

@{CMmes1}     Get Element Text   ${root}  ${Xpath}
@{CMmes2}     Get Element Text   ${root}  ${Xpath}
...
Set  ${root}  ${CMmes1}  \  GM/BODY/CMss[1]/message
Set  ${root}  ${CMmes2}  \  GM/BODY/CMss[2]/message

没问题。关键是我有 2 个 CMme，而不是 CMes 中的 2 条消息。
