Algorithm

Selection

Set1

All the <a> tags with a "href" attribute, with children (a[href]:has(*) )

Set2

All the elements of Set1 with own text or with more than 1 child or with only one child not of type <img>, <canvas>, <svg> or <object> (where "img , object[type^=image], object[data^=data:image], object[data$=png], object[data$=jpeg], object[data$=jpg],object[data$=bmp], object[data$=gif], canvas, svg" returns empty)

Set3

All the elements of Set2 with a not empty text and a "title" attribute

Process

Test1

For each element of Set3, we check whether the "title" attribute is not empty

For each element returning false in Test1, raise a MessageA

Test2

For each element of Set3, we check whether the "title" attribute doesn't only contain non alphanumerical characters.

For each element returning false in Test2, raise a MessageB

Test3

For each element of Set3, we check whether the "title" attribute value doesn't belong to the text link blacklist.

For each element returning false in Test3, raise a MessageB

Test4

For each element of Set3, we check whether the "title" attribute is not striclty identical to the link text.

For each element returning false in Test4, raise a MessageB

Test5

For each element of Set3, we check whether the "title" attribute contains the link text and more.

For each element returning true in Test5, raise a MessageC

For each element returning false in Test5, raise a MessageD

MessageA : Empty "title" attribute of link

• code : EmptyLinkTitle
• status: Failed
• parameter : link text, "title" attribute, snippet
• present in source : yes

MessageB : Not Pertinent link "title" attribute

Failed

• At least one combined link has an empty "title" attribute text content which is blacklisted (Test1 returns false for at least one element)
• At least one combined link has "title" attribute only composed of non alphanumerical characters (Test2 returns false for at least one element)
• At least one combined link has a "title" attribute which is blacklisted (Test3 returns false for at least one element)
