Advanced example with Text Input Problem

[pyrog]

Could you provide an example of case sensitivity and/or regular expressions please?

I'am a french user of several moocs that don't use theses options. The user experience is downgraded, students write a lot of posts to complain.

Part of a real example (the real list is longer 😉) :

<problem>
    <stringresponse answer="obstacle" type="cs">
        <label>Citez les 5 risques ferroviaires</label>
        <description>Sous la forme article défini + nom du risque</description>
        <additional_answer answer="Obstacle"></additional_answer>
        <additional_answer answer="Obstacles"></additional_answer>
        <additional_answer answer="obstacles sur voie"></additional_answer>
        <additional_answer answer="un obstacle sur la voie"></additional_answer>
        <additional_answer answer="des obstacles sur la voie"></additional_answer>
        <additional_answer answer="obstacles"></additional_answer>
        <additional_answer answer="Obstacle"></additional_answer>
        <additional_answer answer="Obstacles"></additional_answer>
        <additional_answer answer="l'obstacle"></additional_answer>
        <additional_answer answer="les obstacles"></additional_answer>
        <additional_answer answer="L'obstacle"></additional_answer>
        <additional_answer answer="Les obstacles"></additional_answer>
        <additional_answer answer="La rencontre d'obstacle"></additional_answer>
        <additional_answer answer="la rencontre d'obstacle"></additional_answer>
        <additional_answer answer="La rencontre d'obstacles"></additional_answer>
        <additional_answer answer="la rencontre d'obstacles"></additional_answer>
        <additional_answer answer="La rencontre d'un obstacle"></additional_answer>
        <additional_answer answer="la rencontre d'un obstacle"></additional_answer>
        <additional_answer answer="percuter un obstacle"></additional_answer>
        <additional_answer answer="Percuter un obstacle"></additional_answer>
        <additional_answer answer="obstacles sur voie"></additional_answer>
        <additional_answer answer="un obstacle sur la voie"></additional_answer>
        <additional_answer answer="des obstacles sur la voie"></additional_answer>
        <additional_answer answer="obsatcles sur la voie "></additional_answer>
        <additional_answer answer="obstacles sur les voies"></additional_answer>
        <additional_answer answer="des obstacles sur les voies"></additional_answer>
        <additional_answer answer="un obstacle sur les voies"></additional_answer>
    </stringresponse>
</problem>

I guess that we could rewrite it simply like this:

<problem>
    <stringresponse answer="obstacle" type="ci regexp">
        <label>Citez les 5 risques ferroviaires</label>
        <description>Sous la forme article défini + nom du risque</description>
        <additional_answer answer=".*obstacle.*"></additional_answer>
    </stringresponse>
</problem>

I think that the answer "un obstacle sur les voies" is not valid so I used an additional answer containing a "real" regexp.
Does this additional answer is valid?
