[Xmlstar-devel] workaround to achieve XHTML-compatible output

[Thorsten G. <tg...@de...>]

Hi everyone,

perhaps the other heavy xmlstarlet users are also interested
in this, so I decided to share.

I wrote an LD_PRELOADable library (sorry, Macintosh users) that
can be used to make xmlstarlet fo/sel output a space before the
“/>” as is needed for XHTML.

https://mbsd.evolvis.org/cvs.cgi/contrib/hosted/tg/forceXHTML.c?rev=HEAD

This was not entirely simple as many useful functions for minimal
change are not exposed by the API; “fo” is a tad more fragile than
“sel” but I tested both on a small corpus and diff’d against the
normal results, but I don’t have PIs or anything else fancy in there.

I tested these on Debian GNU/Linux 11 (“bullseye”). These might even
work with other tools (xmllint/xsltproc) but I don’t use them, only
xmlstarlet, have “always” been.

Maybe drop me a note if you enjoy it, have patches or suggestions.

bye,
