Have you seen that there is a preprocessor for PXP that allows you to
embed XML in ocaml?

http://projects.camlcity.org/projects/dl/pxp-1.2.1/doc/manual/html/ref/Intro_preprocessor.html

I'm happily using this for dynamic web pages. The syntax is more
light-weight, though, e.g. you write

<div> [ ... ]

instead of <div>...</div>, and there is a distinction in the syntax
between node and list of nodes, e.g.

<div> list

but

<div> [ node1 node2 ... ]
