What a terrible XML representation...
Anyway I don't know how much you need but to select the A: types you need:
/message/text[starts-with(., 'A:')]
and for B: ones:
/message/text[starts-with(., 'B:')]
So create an XSLT that use xsl:apply-templates to these two selections. In a 
matching template for A:
<xsl:template match="text[starts-with(., 'A:']">
you can add the HTML markup and similarly for the B: group.
