Test description :

On each Web page, does each downloading functionality for an electronic document pass one of the conditions below (except in special cases)?

Level :

Technical description

Scope :
Decision level :



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)



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 Message1


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 Message2.


If Test2 returns true (all the links have a well-defined extension that belongs to the office document extension list), 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 Message3.

Message1: Office Document Detected
  • code : OfficeDocumentDetected
  • status: NMI
  • parameter : href title attribute, title attribute, snippet
  • present in source : yes
Message2: Check manually links without extension
  • code : CheckManuallyLinkWithoutExtension_Aw22-13071
  • status: NMI
  • present in source : no
Message3: Check downloadable document from form
  • code : CheckDownloadableDocumentFromForm_Aw22-13071
  • status: NMI
  • present in source : no



  • Set2 is empty (the page has no link that are not anchor)
  • Test3 returns true (all the links of the page have a well-defined extension AND all the extension are of office document type AND the page has no form)


In all other cases


We assume that a targetted document (pointed by the "href" attribute of the link) can be characterized by its extension.
