When is Webview 2 based on Edge (Chromium) going to be finalized and what's the current status?
This article https://docs.microsoft.com/en-us/microsoft-edge/hosting/webview2 was updated 7 months ago. at that time it was tagged (developer preview) but now Edge stable is released, so does it mean Webview2 is also finalized? Also, Will Webview 2 lay the groundwork for Windows SETS? I've heard rumors that Microsoft has been waiting to finish Webview2 and then roll out Windows SETS to insiders.
WebView2 HTML parsing
The code below embeds a web-scraping test URI into a Webview2 control. The button2 function returns the links for the site, but requires a redundant Invoke-WebRequest. I know Webview2 does not have an internal DOM capability and the $htmlContent = $WebView2.ExecuteScriptAsync() to return HTML is commented out as it does not appear to work. Is there a way to obtain the html without the Invoke-WebRequest()? function button1 { $title = 'Enter New URL to Navigate To' $msg = 'Please enter URL as https://[...some site...].com/.net/.org' $url = [Microsoft.VisualBasic.Interaction]::InputBox($msg, $title) $url if ($url -ne "") { try { $WebView2.Source = $url $WebView2.Refresh() } catch { $pop.popup("Invalid or Unuseable URL",2,"Error",4096) } } } function button2 { $links = ( Invoke-WebRequest -Uri $WebView2.Source).Links.Href | Get-Unique $regex = '/product*' $links | Select-String $regex | Select line | Out-Gridview -Title "Webpage Links for Products" -PassThru #$pop.popup("Code for Scraping Links",2,"Message",4096) } ######################################################################################################################## $pop = New-Object -ComObject wscript.shell New-Variable -Name 'data' -Value "$([Environment]::GetEnvironmentVariable('LOCALAPPDATA'))\Webview2" -Scope Global -Force $path=$PSScriptRoot # Get DLLs $WinForms = "$path\Microsoft.Web.WebView2.WinForms.dll" $Core = "$path\Microsoft.Web.WebView2.Core.dll" <# $loader = "$path\WebView2Loader.dll" $wpf = "$path\Microsoft.Web.WebView2.Wpf.dll" #> Add-Type -AssemblyName Microsoft.VisualBasic Add-Type -Path $WinForms #Add-Type -Path $Core Add-Type -AssemblyName System.Windows.Forms Add-Type -AssemblyName System.Drawing $Form = New-Object System.Windows.Forms.Form $button1 = New-Object System.Windows.Forms.Button $button2 = New-Object System.Windows.Forms.Button $cancelButton = New-Object System.Windows.Forms.Button # $button1.Location = New-Object System.Drawing.Point(23, 25) $button1.Name = "button1" $button1.Size = New-Object System.Drawing.Size(75, 23) $button1.TabIndex = 0 $button1.Text = "New URL" $button1.BackColor = "Green" $button1.ForeColor = "White" $button1.AutoSize = $true # $button2.Location = New-Object System.Drawing.Point(312, 25) $button2.Name = "button2" $button2.Size = New-Object System.Drawing.Size(75, 23) $button2.TabIndex = 1 $button2.Text = "Links" $button2.BackColor = "Green" $button2.ForeColor = "White" $button2.AutoSize = $true # $cancelButton.Location = New-Object System.Drawing.Point(684, 25) $cancelButton.Name = "button3" $cancelButton.Size = New-Object System.Drawing.Size(75, 23) $cancelButton.TabIndex = 2 $cancelButton.Text = "Close" $cancelButton.BackColor = "Red" $cancelButton.ForeColor = "White" $cancelButton.Text = 'Close Window' $cancelButton.AutoSize = $true $cancelButton.DialogResult = [System.Windows.Forms.DialogResult]::Cancel $Form.CancelButton = $cancelButton # $WebView2 = New-Object -TypeName Microsoft.Web.WebView2.WinForms.WebView2 $WebView2.CreationProperties = New-Object -TypeName 'Microsoft.Web.WebView2.WinForms.CoreWebView2CreationProperties' $WebView2.CreationProperties.UserDataFolder = $data #keeps it out of $PSScriptRoot $WebView2.Source = "https://www.scrapingcourse.com/ecommerce/" $Webview2.Location = New-Object System.Drawing.Point(23, 65) $Webview2.Size = New-Object System.Drawing.Size(749, 373) $WebView2.Anchor = 'top,right,bottom,left' <#navigation complete $WebView2_NavigationCompleted = { $htmlContent = $WebView2.ExecuteScriptAsync("window.chrome.webview.postMessage(document.documentElement.outerHTML;").Result #$htmlContent = $webView2.CoreWebView2.ExecuteScriptAsync("document.documentElement.outerHTML;").Result Write-Host $htmlContent } $WebView2.add_NavigationCompleted($WebView2_NavigationCompleted) $WebView2.add_WebMessageReceived({ param($WebView2, $message) $pop.popup($message.TryGetWebMessageAsString(),3,"Message",4096) }) #> $Form.ClientSize = New-Object System.Drawing.Size(800, 450) $Form.Controls.Add($Webview2) $Form.Controls.Add($cancelButton) $Form.Controls.Add($button2) $Form.Controls.Add($button1) $Form.Name = "Form" $Form.Text = "Webview Web Scraping Sample" $button1.add_click( { button1 }) $button2.add_click( { button2 }) $result=$Form.ShowDialog() #Terminate if Cancel button pressed if ($result -eq [System.Windows.Forms.DialogResult]::Cancel) { [System.GC]::Collect() [System.GC]::WaitForPendingFinalizers() $form.Dispose() Exit } ########################################################################################################################
