  • 1.  Automate a website which uses Shadow DOM

    Posted 03/14/22 12:43 PM
    Hi

    does anyone has any experience in using IBM RPA against a website which heavily uses Shadow DOM (for instance sites which are build with Nuxeo CMS)?
    I am not a web developer and to be honest, I heard about Shadow DOM for the first time today.
    It seems to be a technique to encapsulate some functionalities used in web application but as a result these components do not have a "normal" selector which can be used while automating.
    For the moment I am stuck so I am hoping that there is someone who has some tips&tricks and can point me to the right direction.
    Thanks in advance,

    Hi Nordine!

    Can you add an example of an url and what elements you are trying to access? I'm not sure I've heard about this technique before but I've worked a lot with RPA and have come across some other dynamic frameworks.

    Hi David

    thanks for your interest.
    The web app that I need to automate is not publicly accessible but I found a website with similar Shadow DOM object, cfr https://books-pwakit.appspot.com/explore

    I am unable to wait for an element or to set a value to the Search field. I have tried selectors based on full Xpath, CSS, ...

    defVar --name bElementExists --type Boolean
webStart --name TEST --type "Chrome"
webNavigate --url "https://books-pwakit.appspot.com/explore"
webWaitElement --selector "XPath" --xpath "/html/body/book-app//app-header/app-toolbar[2]" bElementExists=value
logMessage --message "Element exists: ${bElementExists}" --type "Info"
webSet --value hello --selector "CssSelector" --css "#input" --simulatehuman
webClose --name TEST --leavebrowseropen​

    I can see why elements are not picked up by the tool. Normal xpath's don't apply here.

    Try a "Run JavaScript" activity and script you actions using lines like:
    document.querySelector('book-app').shadowRoot.querySelector('#input').value=''...'

    (I only tested it in chrome, not in the Studio)

    I think it's either that, image recognition, or sending keystrokes.

    Hi David

    thanks again for your response.
    Although the "Run Javascript"-option seems to work for setting an input value, I am still unable to actually search for books (in the book app example). I will investigate it further but it will be hard to use this technique for the automation I need to do because that involves different kinds of components (checkboxes, dropdow lists, tables, ...)

    Hi Nordine! Try this.. (Your computer must be ate 1920 x 1080p resolution, windows zoom must be at 100% and Google Chrome zoom at 100% )

    webStart --name TEST --type "Chrome"
    webNavigate --url "https://books-pwakit.appspot.com/explore"
    webWait
    mouse --mode "Click" --resolution "Absolute" --point "933,541"
    sendKeys --keys teste
    keyboard --type "KeyPress" --key "Return"
    keyboard --type "KeyUp" --key "Return"
    webClose --name TEST --leavebrowseropen

    Hi Filipe

    Thanks for your response.
    The appspot.com URL is just an example of a website which uses ShadowDOM. I used this example to demonstrate that IBM RPA is not able to use a selector in that case. Or at least, I don't know how I can make IBM RPA use a selector.
    For the actual application that I need to automate, surface automation (using keystrokes, mouse clicks or image recognition) is not an option because the navigation is quite complication (dynamic dropdown list, checkboxes) and involves interpreting a table.

    Unfortunately, IBM RPA does not support shadow dom. Please raise an idea for it: https://dba.ideas.ibm.com/ideas?project=WDGRPA
