Ah, the reasoning was in a different email, I should have copied at least part of it into the commit message for this patch: xsltproc --nonet -o ./ ./newapi.xsl ./libvirt-api.xml works (outputs 4 *.html files into ./), while: xsltproc --nonet -o ./devhelp/ ./devhelp/devhelp.xsl ./libvirt-api.xml outputs 4 *.html files into ./devhelp but then tries to write to ./devhelp/ as a file (hence the I/O error) rather than writing output to the fifth file devhelp/libvirt.devhelp. That's because XSLT allows for two ways of generating the output of transformation. Either implicit, which xsltproc prints to stdout and can be redirected to a file using -o file. Or explicit, which means the stylesheet contains <xsl:document> element(s) which specifies where the output should be saved. This can be used for generating more files by a single run of xsltproc and -o directory/ can change the directory where the output files will be stored. And since this is cool, why not combine these two approaches in a single file? And that's exactly what happened in devhelp.xsl. It generates 4 html files explicitly and one xml file implicitly. So -o can't ever work for this. Jirka -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
