Ta’rif va qo‘llanilishi
<xsl:message> elementi natijaga xabar yozadi. Bu element asosan xatolar haqida xabar berish uchun ishlatiladi.
Bu element deyarli har qanday boshqa XSL elementini (<xsl:text>, <xsl:value-of> va h.k.) o‘z ichiga olishi mumkin.
terminate atributi xato yuz berganda qayta ishlashni to‘xtatish yoki davom ettirishni tanlash imkonini beradi.

Ixtiyoriy. "yes" xabar natijaga yozilgandan keyin qayta ishlashni to‘xtatadi. "no" xabar natijaga yozilgandan keyin qayta ishlashni davom ettiradi. Standart qiymat — "no". |

artist bo‘sh string ekanligini tekshiring. Agar shunday bo‘lsa, XSL protsessordan chiqamiz va xabar ko‘rsatamiz:
<?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>
<xsl:for-each select="catalog/cd">
<p>Title: <xsl:value-of select="title"/><br />
Artist:
<xsl:if test="artist=''">
<xsl:message terminate="yes">
Error: Artist is an empty string!
</xsl:message>
</xsl:if>
<xsl:value-of select="artist"/>
</p>
</xsl:for-each>
</body>
</html>
</xsl:template>
