Convert HTML Tags Using XSL

[blg]

I am working with an xml document that has html tags embedded in it. The character entities that are embedded in the html need to be converted to tags:

For example, the following character entities are part of the html:

’

—

 

 

I need to perform these conversions
Convert '’' to '’'

Convert '—' to '—'

Convert ' ' to ' '

 

I have successfully converted these 3 character entities in the DTD by adding entity declarations. For example:

<!ENTITY rsquo "’">

 

I will be receiving these xml documents frequently, and the html text changes, so there will probably be additional character entities (beyond the 3 above) that require conversion.

 

Is there another way to perform these character entity conversions without having to add an entity declaration in the DTD for each one?
