XSLT <for-each>
<xsl:for-each> elementi XSLT’da sikl bajarish imkonini beradi.
<xsl:for-each> elementi
XSL <xsl:for-each> elementi yordamida belgilangan tugunlar to‘plamidagi har bir XML elementini tanlash mumkin:
Misol
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<h2>My CD Collection</h2>
<table border="1">
<tr bgcolor="#9acd32">
<th>Title</th>
<th>Artist</th>
</tr>
<xsl:for-each select="catalog/cd">
<tr>
<td><xsl:value-of select="title"/></td>
<td><xsl:value-of select="artist"/></td>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>

Eslatma: select atributining qiymati XPath ifodasidir. XPath ifodasi fayl tizimi bo‘ylab harakatlanishga o‘xshab ishlaydi: unda to‘g‘ri qiya chiziq (/) quyi kataloglarni tanlaydi.
Natijani filtrlash
<xsl:for-each> elementidagi select atributiga shart qo‘shib, XML fayldan olinadigan natijani filtrlashimiz ham mumkin.
<xsl:for-each select="catalog/cd[artist='Bob Dylan']">
Ruxsat etilgan filtr operatorlari:
- = (teng)
- != (teng emas)
- < kichik
- > katta
