XML (Extensible Markup Language) e un format special de trimitere si stocare date in fisiere cu extensia .xml, cu o sintaxa bazata pe tag-uri. Documentele XML sunt de obicei folosite in aplicatii web de accesare date de la un server la altul.
Acest tutorial arata cum puteti prelua date dintr-un fisier XML si sa le afisati in pagina web, folosind jQuery Ajax.
