Alert if a certain tag is missing in the page source

User question:

> How to check a web page for the absence of a particular meta tag?

> If it's missing, alert me.

> Concretely, if this tag is missing, I would like to know about it:



This is possible via a plugin.


The following plugin only checks the availability of that tag and does not monitor changes in the page content. So you will only get a notification if this tag is missing.


Sub Wsw_BeforeCheck(Handle)

   'Disable optimizations and always check this bookmark by content

   Bookmark_SetProperty(Handle, "checkmethod", "content")

End Sub


Sub Wsw_CompareVersions(Handle, ByRef sMemWeb, ByRef sMemLocal, ByRef sStatusMessage, ByRef iStatusCode)

   'default value of iStatusCode is 0 (=no update)


   Dim bFound = InStr(UCase(sMemWeb), "<META NAME=""ROBOTS"" CONTENT=""NOINDEX, NOFOLLOW"">") > 0


   If bFound = False Then

      'Tag not found -> alert update

      iStatusCode = 1

      sStatusMessage = "TAG not found"

   End If

End Sub
