Aide pour parser tableau avec DOmdocument
bonjour
pouvez vous me dire s'il est possible (avec DomDocument et php) de recuperer les données presentes uniquement dans les tableaux ayant pour class='tableauOK' sachant que:
- le nb de tableaux ayant pour class='tableauOK' peut varier
**- le nb de tableaux ayant pour class="SYSTEM" peut aussi varier **
ci dessous le code html à parser et le debut de code
mais je ne vois pas comment faire pour recuperer les données que des tableaux avec class='tableauOK'.
On m'a parle de DOMXPath mais je ne vois pas comment faire
merci pour votre aide
