Scope
Page
Decision level
Semi-Decidable
Algorithm
Selection
Set1
All the <a>
tags with an "href"
attribute (a[href])
Set2
All the elements from Set1 with an "href"
attribute that does not contain a fragment (presence of the hash sign (#))
Set3
All the elements from Set2 that have a proper extension (no parameters, a path after the domain that contains a "." character)
Set4
All the <form>
tags (form)
Process
Test1
For each element of Set3, we check whether the content of the "href"
attribute of the link ends with an extension that belongs to the office document extension list
For each element returning true in Test1, raise a MessageA
Test2
If Test1 returns false, we check whether the size of Set2 is equals to size of Set3. In other words, we verify that all the links of the page have a well-defined extension.
If Test2 returns false (some links have no extension on the page), raise a MessageB.
Test3
If Test2 returns true (all the links have a well-defined extension), we check whether Set4 is empty (the page contains forms that may lead to a downloadable document).
If Test3 returns false (some form are found on the page), raise a MessageC.
MessageA : Office Document Detected
- code : OfficeDocumentDetected
- status: Pre-Qualified
- parameter : href attribute, snippet
- present in source : yes
MessageB : Check manually links without extension
- code : CheckManuallyLinkWithoutExtension_Rgaa30-13071
- status: Pre-Qualified
- present in source : no
MessageC : Check downloadable document from form
- code : CheckDownloadableDocumentFromForm_Rgaa30-13071
- status: Pre-Qualified
- present in source : no
Analysis
Not Applicable
- The page has no link that are not anchor (Set2 is empty)
- All the links of the page have a well-defined extension AND all the extension are not of office document type AND the page has no form (Test3 returns true)
Pre-Qualified
In all other cases
Notes
We assume that a targetted document (pointed by the "href"
attribute of the link) can be characterized by its extension.
