Hi Jack,
I have done the same to validate an XML document with an schematron. I think
that it would be also useful to get the XPATH path of the errors in the XML
output. The template which does this is done in skeleton1-5 (<axsl:template
match="*|@*" mode="schematron-get-full-path">); so you have to call it from
the assert template:
<xsl:template match="sch:assert | assert">
<xsl:if test="not(@test)">
<xsl:message>Markup Error: no test attribute in
<assert></xsl:message>
</xsl:if>
<axsl:choose>
<axsl:when test="{@test}"/>
<axsl:otherwise>
<error> <!--my xml output-->
<message> <!--my xml output-->
<xsl:call-template name="process-assert">
<xsl:with-param name="role" select="@role"/>
<xsl:with-param name="id" select="@id"/>
<xsl:with-param name="test"
select="normalize-space(@test)" />
<xsl:with-param name="icon" select="@icon"/>
<xsl:with-param name="subject" select="@subject"/>
<xsl:with-param name="diagnostics"
select="@diagnostics"/>
</xsl:call-template>
</message>
<location> <!--my xml output-->
<axsl:apply-templates mode="schematron-get-full-path"
select="self::*"/> <!--XPATH path of the error-->
</location>
</error>
</axsl:otherwise>
</axsl:choose>
</xsl:template>

> <sch:assert test="(@Title = 'Mr' and Sex = 'Male') or @Title != 'Mr'">
> <sch:error>If the Title is "Mr" then the sex of the person must be
"Male".</sch:error>
> </sch:assert>
