No, there are no standard XPath ways to create a new node.
But, given a function in the context of the XPath evaluator, this is possible:
<xsl:stylesheet version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:my="my:my" exclude-result-prefixes="my xs">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<xsl:sequence select=
"let $print := function () as element()
{
my:element('Hello', (), 'World')
}
return ($print())
"/>
</xsl:template>
<xsl:function name="my:element" as="element()">
<xsl:param name="pName" as="xs:string"/>
<xsl:param name="pAttributes" as="attribute()*"/>
<xsl:param name="pText" as="xs:string?"/>
<xsl:element name="{$pName}">
<xsl:sequence select="$pAttributes"/>
<xsl:sequence select="$pText"/>
</xsl:element>
</xsl:function>
</xsl:stylesheet>
produces:
<Hello>World</Hello>
Similarly, the function my:element() can be written in XQuery.

Hi Folks,
I want to create an anonymous XPath function that returns markup. For example:
let $print := function ()
{
<hello>World</hello>
}
return ($print())
I tried embedding that XPath within an xsl:sequence element:
<xsl:sequence select="
let $print := function ()
{
<hello>World</hello>
}
return ($print())
" />
but that produced this error message:
The value of attribute "select" associated with an element
type "xsl:sequence" must not contain the '<' character.
So I escaped the '<' characters:
<xsl:sequence select="
let $print := function ()
{
<hello>World</hello>
}
return ($print())
" />
and that produced this error message:
Unexpected token "<" in path expression
Is it possible to create an anonymous function that returns markup?
If yes, how?
