Set HTML5 doctype with XSLT
I think this is currently only supported by writing the doctype out as text: <?xml version=”1.0″ encoding=”utf-8″?> <xsl:stylesheet version=”1.0″ xmlns:xsl=”http://www.w3.org/1999/XSL/Transform”> <xsl:output method=”html” encoding=”utf-8″ indent=”yes” /> <xsl:template match=”https://stackoverflow.com/”> <xsl:text disable-output-escaping=’yes’><!DOCTYPE html></xsl:text> <html> </html> </xsl:template> </xsl:stylesheet> This will produce the following output: <!DOCTYPE html> <html> </html>
