Presumably there might be a lot of resource elements with different
identifiers? If so, it's probably easiest to create a key that indexes
the resource elements by their identifiers as follows:

<xsl:key name="resources" match="resource" use="@identifier" />

You can then get a particular resource based on its identifier with:

  key('resources', $identifier)

So, for example, if you're on an item element at the moment, you can
get the resource referenced by that item element's identifierref
attribute using:

  key('resources', @identifierref)

I'd store that resource in a variable and then test whether the
variable contains anything:

<xsl:template match="item">
  <xsl:variable name="resource"
                select="key('resources', @identifierref)" />
  <xsl:if test="$resource">
    ...
  </xsl:if>
</xsl:template>

You should find this easy enough. The resource element's href
attribute can be accessed with $resource/@href.
