Example: Generating a Custom Error Message

Using a commit script, write a custom error message that appears when the description statement is not included at the [edit interfaces t1-fpc/pic/port] hierarchy level:

<?xml version="1.0" standalone="yes"?>

<xsl:stylesheet version="1.0"

    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 

    xmlns:junos="http://xml.juniper.net/junos/*/junos" 

    xmlns:xnm="http://xml.juniper.net/xnm/1.1/xnm" 

    xmlns:jcs="http://xml.juniper.net/junos/commit-scripts/1.0">

    <xsl:import href="../import/junos.xsl"/>

    <xsl:template match="configuration">

        <xsl:variable name="interface" select="interfaces/interface"/>

        <xsl:for-each select="$interface[starts-with(name, 't1-')]"> 

            <xsl:variable name="ifname" select="."/>

            <xsl:if test="not(description)">

                <xnm:error>

                    <xsl:call-template name="jcs:edit-path"/>

                    <xsl:call-template name="jcs:statement"/>

                    <message>Missing a description for this T1 interface.</message>

                </xnm:error>

            </xsl:if>

        </xsl:for-each>

    </xsl:template>

</xsl:stylesheet>
