if

XSLT <xsl:if> elementi

Ta’rif va qo‘llanilishi

<xsl:if> elementi faqat ko‘rsatilgan shart rost (true) bo‘lgandagina qo‘llaniladigan shablonni o‘z ichiga oladi.

Maslahat: Bir nechta shartli tekshiruvlarni ifodalash uchun <xsl:choose> elementidan <xsl:when> va <xsl:otherwise> bilan birgalikda foydalaning!

Sintaksis

<xsl:if test="expression">  </xsl:if>

Atributlar

Atribut	Qiymat	Tavsif
test	expression	Majburiy. Tekshiriladigan shartni belgilaydi
