Saxon

We are using Saxon-HE in one of our .NET projects. We’ve noticed recently the following issue – when ‘value-of’ is applied to multiple nodes as below

XSLT:

<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" version="2.0">
  <xsl:template match="/">
    <data>
      <value id="febf90c4">
        <xsl:attribute name="value">
          <xsl:value-of select="/Clients/Client1/Personal/Initial" />
        </xsl:attribute>
      </value>
    </data>
  </xsl:template>
</xsl:transform>

Input XML:

<Clients>
  <Client1 Id="6180657">
    <Personal Id="6180657">
      <Initial>
        <FirstName type="q5:string">M</FirstName>
        <LastName type="q6:string">P</LastName>
      </Initial>
    </Personal>
  </Client1>
</Clients>

the transformation produces incorrect result

Output XML:

<data xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <value id="febf90c4" value="&#xA;        M&#xA;        P&#xA;      " />
</data>

Expected XML:

<data xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <value id="febf90c4" value="MP" />
</data>

I assume concatenation of several nodes includes indentation characters into the output value.
