I tried so:
<xsl:text> <xsl:text> — have no space character in html code;
<xsl:text> <xsl:text> — don’t work, XSLT processor error “Entity ‘nbsp’ not defined.”;
<xsl:text>&nbsp;<xsl:text> — obtained &nbsp; in html code, but no space character;
<xsl:text><![CDATA[ ]]> <xsl:text> — have no space character in html code;
<xsl:text><![CDATA[&]]>nbsp; <xsl:text> — &nbsp; in html code, but no space character;
<xsl:text><![CDATA[ ]]> <xsl:text> — &nbsp; in html code, but no space character;
Finaly, I decided this by inserting <![CDATA[ ]]> into XSLT, and then seting attribute “disable-output-escaping” in XSLT to “yes”. But I suppose this solution is not the best one.
Сorrect code: <xsl:text disable-output-escaping=”yes”><![CDATA[ ]]></xsl:text>
