Level
AAA
Technical description
Scope
Page
Decision level
Semi-Decidable
Algorithm
Selection
Set1
All the <a> tags with a "href" attribute, with children (a[href]:has(*) )
Set2
All the elements of Set1 without own text and with only one child of type <svg>(svg)
Set3
All the elements of Set2 with a not empty text.
Process
Test1
For each element of Set2, 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 Set2, 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
MessageA : Unexplicit Link
- code : UnexplicitLink
- status: Failed
- parameter : link text,
"title"attribute, snippet - present in source : yes
MessageB : Check link without context pertinence
- code : CheckLinkWithoutContextPertinence
- status: Need More Info
- parameter : link text,
"title"attribute, snippet - present in source : yes
Analysis
Not Applicable
The page has no svg link (Set1 is empty)
Failed
At least one svg link has a text content which is blacklisted or that only contains non alphanumerical characters (Test1 OR Test2 returns false for at least one element)
Pre-Qualified
In all other cases
Notes
We assume here that the svg links have only one child of type <svg>
