XSL Komutlarnın Örnekleri

Bana bir xslt için örnek kodların makalasi lazım. Bunuda karma yapacağım ama Burak Selim Şenyurt her zamanki gibi harika bir makale ile anlatmış ne nedir diye.

Bende gördüğüm güzel örnekleri parça parça burada toplayacağım.

XML verisi aşağıdaki gibi olsun demiş BSY:

<?xml version="1.0" encoding="utf-8" ?>

<Muzikler>

    <Muzik ID="1">

        <Soyleyen>Coldplay</Soyleyen>

        <AlbumAdi>X and Y</AlbumAdi>

        <CikisTarihi>2005</CikisTarihi>

        <Fiyat>28</Fiyat>

        <Tip>CD</Tip>

    </Muzik>

    <Muzik ID="2">

        <Soyleyen>Depeche Mode</Soyleyen>

        <AlbumAdi>Playing The Angel</AlbumAdi>

        <CikisTarihi>2005</CikisTarihi>

        <Fiyat>25</Fiyat>

        <Tip>CD</Tip>

    </Muzik>
