Hello, I'm trying to create a text file from some XML using Lib::XSLT, my transformation works fine except Lib::XSLT adds an extra <?xml version="1.0"?> line to the start of the file, how can I stop it doing this? Here's my XSLT: 
<xslt:stylesheet version="1.0" xmlns:data="http://www.SDMX.org/resourc
+es/SDMXML/schemas/v2_0/generic" xmlns:xslt="http://www.w3.org/1999/XS
+L/Transform" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xm
+lns:message="http://www.SDMX.org/resources/SDMXML/schemas/v2_0/messag
+e" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" omit-xml-declaration="yes"/>
<xslt:param name="sep">|</xslt:param>
<xslt:output method="text" />
<xslt:template match="message:MessageGroup">
<xslt:for-each select="data:DataSet">
<!-- get dimensions (but not time) and store in dimensions variable --
+>
<xslt:for-each select="data:Series">
<xslt:variable name="dimensions">
<xslt:for-each select="data:SeriesKey">
<xslt:for-each select="data:Value">
<xslt:value-of select="@value" />
<xslt:value-of select="$sep" />
</xslt:for-each>
</xslt:for-each>
</xslt:variable>
<!--get obs statuses and store in obs statuses variable-->
<xslt:variable name="obsStatuses">
<xslt:for-each select="data:Attributes">
<xslt:for-each select="data:Value">
<xslt:value-of select="@value" />
</xslt:for-each>
</xslt:for-each>
</xslt:variable>
<!--write out dimensions variable, time, observation, obsstatuses vari
+able-->
<xslt:for-each select="data:Obs">
<xslt:value-of select="$dimensions" />
<xslt:value-of select="data:Time" />
<xslt:value-of select="$sep" />
<xslt:value-of select="data:ObsValue/@value" />
<xslt:value-of select="$sep" />
<xslt:value-of select="data:Attributes/data:Value/@value"/>
<xslt:text>
</xslt:text>
</xslt:for-each>
</xslt:for-each>
</xslt:for-each>
</xslt:template>
</xslt:stylesheet>

Here's the Perl: 
my $parser = XML::LibXML->new();
    my $xslt = XML::LibXSLT->new();
    my $source = XML::LibXML->load_xml(location => "$xmlFile");
    my $style_doc = $parser->parse_file(Path::Class::File->new("$xsltF
+ile"));
    my $stylesheet = $xslt->parse_stylesheet($style_doc);
    open OUTPUTFILE, ">>$outputFile" or die("Unable to open $outputFil
+e, $!");
    print OUTPUTFILE $stylesheet->transform($source);
    close OUTPUTFILE;
