Decision level

Semi-Decidable

Algorithm

Selection

Set1

All the <a> tags with a "href" attribute, without children (a[href]:not(:has(*)) )

Set2

All the elements of Set1 with a not empty text.

Process

Test1

For each element of Set3, we check whether the link content doesn't belong to the text link blacklist.

For each element returning false in Test1, raise a MessageA, raise a MessageB instead.

Test2

For each element of Set3, we check whether the link content doesn't only contain non alphanumeric characters.

For each element returning false in Test2, raise a MessageA, raise a MessageB instead.
