Hi,

I want to know how to include/import one xsl into another xsl. Here one general xsl contains all general processing works, say, "Generate_Response.xsl". It will be used from other two xsls, say, "Clinic.xsl" and "Hospital.xsl". Here how to call the templates present in the "Generate_Response.xsl" in "Clinic.xsl". Thanks in advance for your help.

There are two instructions, xsl:include to include and xsl:import to import stylesheet modules.
See http://www.w3.org/TR/xslt#include and http://www.w3.org/TR/xslt#import
As for using templates defined in an included or imported module, there is no difference doing that, use xsl:apply-templates or xsl:call-template the same as you do with other templates.
Additionally there is xsl:apply-imports (http://www.w3.org/TR/xslt#apply-imports) and in XSLT 2.0 there is xsl:next-match (http://www.w3.org/TR/xslt20/#apply-imports)
