How to make xsl:copy keep html entities literally?

Question

I have an input xml like this:

...    
<member name="&#916;"></member>
...

When I'm applying the identity transformation (i.e. I want to keep this part of the input and I want to change other parts of it) then I get this:

...
<member name="Δ"></member>
...

How can I keep that part literally?

Answer 1

in XSLT 2.0, you can use

<xsl:character-map name="charmap">
    <xsl:output-character character="&#916;" string="&amp;#916;"/>
</xsl:character-map>
