Nested loop in RobotFramework

问题

I need to create a nested loop in Robot framework. Can you please Help me do it?

${contents}=    Get File    ${file path}
 @{lines}=    Split to lines    ${contents}
 ${matched elements}=    Get Webelements    ${LABEL PORTAIL XPATH }
 : FOR    ${element}    IN    @{matched elements}
 \    ${text}=    Get Text    ${element}
 \    : FOR    ${line}    IN    @{lines}
 \    Run Keyword If    '${text}' == '${line}'    Log    '${text} matched'

I need to have a nested loop which compares all the ${text} with all the @{lines} in the file.

Thanks in Advance

No nested loops in RF; that can be done only by calling a keyword with the inner loop, in the outer one.

In your particular case though, you could go without it - as you want to match the full line, that's doable through Should Contain:

${contents}=    Get File    ${file path}
@{lines}=    Split to lines    ${contents}
${matched elements}=    Get Webelements    ${LABEL PORTAIL XPATH }
: FOR    ${element}    IN    @{matched elements}
\  ${text}=     Get Text    ${element}
\  ${present}=  Run Keyword And Return Status    Should Contain    ${lines} 
${text}
\    Run Keyword If  ${present}    Log    '${text} matched'

If you were going after a partial match - i.e. ${text} to be a part of a ${lines} member, then it wouldn't be possible like this.

It isn't possible without custom keyword containing the inner loop. See doc: http://robotframework.org/robotframework/latest/RobotFrameworkUserGuide.html#nested-for-loops

I'd say that such logic should be always written using some stronger language (python, java...) and then just called from RF.

Nested for loops

Having nested for loops is not supported directly, but it is possible to use a user keyword inside a for loop and have another for loop there.

*** Keywords ***
Handle Table
    [Arguments]    @{table}
    :FOR    ${row}    IN    @{table}
    \    Handle Row    @{row}

Handle Row
    [Arguments]    @{row}
    :FOR    ${cell}    IN    @{row}
    \    Handle Cell    ${cell}
