Access next webpage after clicking - regex

Question

Requirement : After clicking on webpage named in $ie.Navigate below. I Need to access HTML / OuterHTML source of Web-page which opens next.
Ex: When I open https://www.healthkartplus.com/search/all?name=Sporanox (by setting $control = Sporanox), below code simply clicks on first matching link. After link is clicked, I need to access HTML of resulting page.
Update : referred another SO question and learned that we can search appropriate window. Code seems to be working for some scenarios but not for all. For $ie2 I get problem accessing Document property.
function getStringMatch
{
# Loop through all 2 digit combinations in the $path directory
foreach ($control In $controls)
{
$ie = New-Object -COMObject InternetExplorer.Application
$ie.visible = $true
$site = $ie.Navigate("https://www.healthkartplus.com/search/all?name=$control")
$ie.ReadyState
while ($ie.Busy -and $ie.ReadyState -ne 4){ sleep -Milliseconds 100 }
$link = $null
$link = $ie.Document.get_links() | where-object {$_.innerText -eq "$control"}
$link.click()
while ($ie.Busy -and $ie.ReadyState -ne 4){ sleep -Milliseconds 100 }
$ie2 = (New-Object -COM 'Shell.Application').Windows() | ? {
$_.Name -eq 'Windows Internet Explorer' -and $_.LocationName -match "^$control"
}
# NEED outerHTML of new page. CURRENTLY it is working for some.
$ie.Document.body.outerHTML > d:\med$control.txt
}
}
$controls = "Sporanox"
getStringMatch

Answer 1

I think the issue is when you look for the links in the first page.
The link innerText is not equal to $control, it contains $control i.e. innerText is "Sporanox (100mg)".
The following might help:
$link = $ie.Document.get_links() | where-object {if ($_.innerText){$_.innerText.contains($control)}}
EDIT
Here is the complete code I'm using:
function getStringMatch
{
# Loop through all 2 digit combinations in the $path directory
foreach ($control In $controls)
{
$ie = New-Object -COMObject InternetExplorer.Application
$ie.visible = $true
$site = $ie.Navigate("https://www.healthkartplus.com/search/all?name=$control")
$ie.ReadyState
while ($ie.Busy -and $ie.ReadyState -ne 4){ sleep -Milliseconds 100 }
$link = $null
$link = $ie.Document.get_links() | where-object {if ($_.innerText){$_.innerText.contains($control)}}
$link.click()
while ($ie.Busy)
{
sleep -Milliseconds 100
}
# NEED outerHTML of new page. CURRENTLY it is working for some.
$ie.Document.body.outerHTML > d:\med$control.txt
}
}
$controls = "Sporanox"
getStringMatch
