XSLT Syntax
content_copy zoom_out_map
<xsl:call-template name="jcs:statement"> <xsl:with-param name="dot" select="expression"/> </xsl:call-template>
SLAX Syntax
content_copy zoom_out_map
call jcs:statement($dot=expression);
Description
Generate a <statement> element suitable for inclusion in an <xnm:error> or <xnm:warning> element. This location
defaults to “ . ”,
the current position in the XML hierarchy. If the error is not at
the current position in the XML hierarchy, you can alter the default
when you call the template by including a valid XPath expression either for the dot parameter
in SLAX scripts or for the select attribute
of the dot parameter in XSLT scripts.
Parameters
dot | XPath expression specifying the hierarchy level. The default
location is the position in the XML hierarchy that the script is currently
evaluating. You can alter the default when you call the template by
including a valid XPath expression either for the |
Usage Examples
The following example demonstrates how to call the jcs:statement template in a commit script:
content_copy zoom_out_map
<xnm:error> <xsl:call-template name="jcs:edit-path"/> <xsl:call-template name="jcs:statement"> <xsl:with-param name="dot" select="mtu"/> </xsl:call-template> <message> <xsl:text>SONET interfaces must have a minimum MTU of </xsl:text> <xsl:value-of select="$min-mtu"/> <xsl:text>.</xsl:text> </message> </xnm:error>
When you commit a configuration that includes a SONET/SDH interface
with a maximum transmission unit (MTU)
setting less than a specified minimum, the <xnm:error> element results in the following CLI output:
content_copy zoom_out_map
[edit] user@host# commit
content_copy zoom_out_map
[edit interfaces interface so-1/2/3] 'mtu 576;' # mtu statement generated by the jcs:statement template SONET interfaces must have a minimum MTU of 2048. error: 1 error reported by commit scripts error: commit script failure
The test of the MTU setting is not performed in the <xnm:error> element. For the full example, see Example: Impose a Minimum MTU Setting.
