Check website for specific string after login using Powershell

Created on the screen

I need to check the page I have logged into

gives me an error saying downloadfile has 2 arguments

This is the login script. It works fine. From here I want to check to see if the login succeeded or failed. So far  the only way I know of to tell is to look for text on the page after login.

Any suggestions would be appreciated.

# Find the username field and set the value to that of our variable
    $usernameField = $doc.getElementById('userName')
      #write-host $usernameField
    $usernameField.value = $username
      write-host $username
    # Find the password field and set the value to that of the result
    # of a call to the get-password function with the paramter defined at top
    $passwordField = $doc.getElementById('password')
      $passwordField.value = $pass
      write-host $pass
    # Find and click the submit button
    $submitButton = $doc.getElementById('login')
      write-host $submitButton
    $submitButton.click()
    # Wait until login is complete
    do {sleep 1} until (-not ($ie.Busy))

This is the problem with your script for me.

$ie.Navigate2('http://something')

I am already logged into the site. I need to search the site  after login.

$doc.Document.getElementById("LoginNotice").innerHTML


The eliment ID I cannot find. As near as I can tell there is not an eliment ID like on the login page.

You will need to wrap the post-login string in a div with an id attribute, (e.g. <div id="loginstring">login successful</div>) and then get the div by ID using the Powershell method above.

Sorry, went about a mile over my head. I have no idea what it is you are trying to tell me to do.

ID= "tbam"

string I want to find = ActivityMonitor

Would this be correct?

$doc.Document.getElementById("tbam").innerHTML
if ($ie.Document.body.innerText -like 'ActivityMonitor')

Keeps erroring because of a null value, should this work?

If ($doc.Document.getElementById("tbam").innerText -ne "null")

This does not error but it does not write to the test file either.

If ($doc.Document.getElementById("tbam").innerText -ne "null")

            {$loginSucceeded, $WebSite -join " " | out-file -filepath c:\MonitorFolder\ServersUp.txt -append}

Here is the line I got the ID from:

<a id="tbam" href="/t2/tbam/activityMonitor.htl?method=showActivityMonitor&screenId=tbam">ActivityMonitor  </a>

Is there maybe a way to download the current page to a file and search the file for test?

I am not the developer. I can talk to them and see if that can be done.

It is in JAVA.

Expanded the code a little more. It looks like the <script[/> tag gets closed. I'm not a programmer so I an not that sure of what I see.

Here is what I have found out:

$doc = $ie.document has to be in the script or I cannot login
$ie.document is the original page before login and that is why I get null for tbam.

Looks like I need to be able to access the page after login to be able to find tbam and get the script to work.

I tool a try with this but the page downloaded is still the page before login.

$WebSite2 = ($WebSite + "/login.htl?method=showLogin")
      write-host $WebSite2
$ie = new-object -com InternetExplorer.Application
# Navigate to the login page
$ie.navigate($WebSite2)
# Wait for the page to finish loading
do {sleep 1} until (-not ($ie.Busy))
$doc2 = $ie.document
$doc2 | out-file "C:\monitorFolder\test62.txt"

Website I can post

https://t2libd1i174.systrends.com/t2/login/chooser.jsp

Not sure how much good it will do without login credentials. I cannot post those, might give access to confidential information.

Making some progress.

$source = $ie.Document.documentElement.outerHTML | out-file "C:\monitorFolder\test6.html"

Downloads most of the page.

Trying to get the page searched for text now.

      If ($result -eq $True) 

Select allOpen in new window

is nonsense, because the result of the IF expression again is $true or $false ;-). The correct usage is a simple

      If ($result) 

Select allOpen in new window

I don't understand. I posted the solution and tried to award the points to the experts. I am happy with the help they provided. Did I click a wrong button?

Experts may not have provided the final answer but they did keep me encouraged to keep trying.

Thank you so much for all the effort.
