Why not use simply

string(.)

where the context node is the Document element? Assuming that in the XSLT
transformation there is this directive:

 <xsl:strip-space elements="*"/>

Here is a complete transformation, given this source XML document:

<Document>
    <binary-value>0100</binary-value>
    <binary-value>11</binary-value>
    <binary-value>1010001</binary-value>
</Document>

Transformation:

<xsl:stylesheet version="1.0" xmlns:xsl="
http://www.w3.org/1999/XSL/Transform";>
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

  <xsl:template match="Document">
    <xsl:sequence select="string(.)"/>
  </xsl:template>
</xsl:stylesheet>


Result:

0100111010001

Thanks,
