document(//a/@href)

<xsl:fallback>
       <xsl:copy-of select='/..'/> 
</xsl:fallback>

or some non-empty node-set which would be added instead of non-existent
file. 


Another simple usercase if non-existent file always returns an error
and if there is at least one right filename in the source document:

<xsl:template name="open">
  <xsl:param name="x"/> 
  <xsl:param name="y"/>
	
 <xsl:apply-templates select="document($x)//aaa">
     <xsl:fallback>
           <xsl:call-template name="open">
                 <xsl:with-param name="x" select="//files[$y]"/>
                 <xsl:with-param name="y" select="$y + 1"/>
            </xsl:call-template>
     </xsl:fallback>
  </xsl:apply-templates>
</xsl:template>
