Retsensioonid

XML retsensioon meeskonnale Muru (1. osa)

XML vastab kõikidele ülesande püstituses seatud nõuetele ning valideerub sellele vastava XSD-ga. Välja on paista, et XSD-d on muudetud vastavalt meeskonna nägemusele ning ei ole tegemist otse Visual Studios genereeritud skeemifailiga. XML failis on olemas vajalikud loogilised dimensioonid ja kasutatakse piisavalt attribuute. Atribuudid on ülesande XML-is küll enamasti andmetüübi kohta kuid kasutakse ära ka andmete järjestuse edastmiseks. Eraldi tooks välja, et eeskujulikult kasutatakse teksti kuvamist CDATA-s.

Esimese transformatsiooniga kuvatakse välja kõik XML-is olevad kontod ning nendega seotud ülekanded. Teises transformatsioonis tehakse kontode jäägi kuvamine kahanevas järjekorras. Mõlemates transformatsioonides on kasutatud enamat kui lihtsalt for-each kausleid. Kasutatakse ära sorteerimist ja kuvatakse viisakas HTML. Kahjuks ei kasutata ära parameetreid, kuid see polnud ka otseselt kohustuslik.

Töö on korralik ja ei leidnud ühtegi märkimisväärset probleemi.
