XSLT 2.0 allows you to validate an element (including a newly constructed element) against a schema, for example

<xsl:import-schema namespace="abc.xyz" schema-location="file://temp.xsd"/>

<xsl:template ...>
   <xsl:element name="x" validation="strict">
     ...
   </xsl:element>
</xsl:template>

Unfortunately there's no way of catching the error if it's invalid. However, Saxon has a try/catch extension for doing this.

How do I check the type of selected value in XSLT?

An XSLT 2.0 Schema-aware (SA) processor can validate against a schema source XML files, output result files, intermediary trees, parameters and variable values, return values from functions or from applying/calling templates.

XSLT 1.0 uses XPath 1.0 which is not strongly typed and has only a few standard types.

This is much easier than validating against a schema.

In XPath 2.0 (XSLT 2.0) use:

$yourVar instance of xs:double

In XPath 1.0 (XSLT 1.0) use:

number($yourVar) = number($yourVar)
