[xslt] Question about white space output

[srperan sherlock dif um es]

Hello. I am using libxslt to process a XML file and output a plain text
file and I need to insert white spaces. I have tried with <xsl:text>
&#160; </xsl:text> but this returns a symbol, not whitespace. I have
read that this is an encoding problem but I can tell to libxslt that the
output must be ISO-8859-1.

I have tried with #x20, #x9, #xD and #xA without results.

Thanks
