فیلترسازی
یکی از خصوصیات دیگری که فایل XML داشت، فیلد ژانر موسیقی بود و قصد داریم با استفاده از فیلترسازی، تنها سبک خاصی مثل سبک پاپ را نمایش دهیم و موسیقی‌هایی را که خارج از این سبک هستند، از نتیجه حذف کنیم. به همین علت دستور for-each را به شکل زیر تغییر میدهیم:

<xsl:for-each select="Albums/Album[contains(Genres/Genre, 'POP')]">

<xsl:for-each select="Albums/Album[not(contains(Genres/Genre, 'POP'))]">

<xsl:for-each select="Genres/Genre">
<xsl:value-of select="."/>
<xsl:if test="position() != last()">
