Re: How do you set the action attribute for an HTML fo

When you rely on the XSLT processor to serialize the result tree in HTML syntax, it's going to make conservative decisions as to how to make abstract elements, attributes, and character data manifest as encoded text with embedded markup. The HTML it produces is intended to be processed by a conforming HTML user agent. A JSP engine is not such an agent. The serializer does know that certain HTML attributes are subject to different kinds of formatting, but it has no way of knowing that instead of one of the standard types of attribute values, you want to insert a completely unescaped JSP tag. > I've followed the suggestion at http://www.dpawson.co.uk/xsl/sect2/N1553.html#d1670e229 > > using: > > <xsl:attribute name="action" saxon:disable-output-escaping="yes" xmlns:saxon="http://icl.com/saxon"> > <xsl:text><%=request.getRequestURI()%></xsl:text> > </xsl:attribute> > > [...] > > This is what I get: > > <form method="get" action="<%25=request.getRequestURI()%25>"> > > And of course I'd like: > > <form method="get" action="<%=request.getRequestURI()%>"> Ordinarily that method would work, but the "action" attribute of an HTML form element is one of those special attributes that is supposed to be a URI reference, so the serializer, thinking it is helping you produce a proper value, is turning "%" into "%25". This behavior is not required by the XSLT spec except for non-ASCII characters, and IMHO it should not be happening at all (e.g., what if you already had properly escaped such characters in your URI?) So I would call this a bug in Saxon. saxon:disable-output-escaping="yes" should, IMHO, disable *all* escaping. > <xsl:attribute name="action"> > <xsl:text disable-output-escaping="yes"><%=request.getRequestURI()%></xsl:text> > </xsl:attribute> That method would definitely not work because xsl:attribute discards the text nodes that were created in its content and only uses their encapsulated text. Escaping only happens at serialization time. The d-o-e flag indicates you'd prefer the serializer to not escape a text node's encapsulated text upon output, but that only applies to the serialization of the text node; it doesn't change the node's encapsulated text at all.
