Re: [xsl] Group problem with blank elements

[Mukul Gandhi <mukul_gandhi@xxxxxxxxx>]

Hi Prakash,
  Your stylesheet look fine.. But when I run it with
Saxon 6.5.3, I get an error -

Error on line 2 column 6 of
file:/C:/xml/xsleg/xslt/posgroup1.xsl:
  Error reported by XML parser: The processing
instruction target matching "[xX]
[mM][lL]" is not allowed.
Transformation failed: Failed to parse stylesheet

Regards,
Mukul
