Re: [libvirt] [PATCH 1/2] maint: use common xml quoting style

According to the official XML specification [1], attributes can be specified with either ' or " (where the difference is that you can use '"' or '"' but must use """, and conversely for "'" or "'" vs. '''). But our code generation in src/conf prefers to output the '' notation, as it is easier to write C string literals for that style. Using a consistent style throughout libvirt will make it easier for users to copy-and-paste without wondering why we switch quoting styles mid-stream. [1] http://www.w3.org/TR/xml11/#NT-Reference Mechanical conversion done with: $ find -name '*.xml' | \ xargs sed -i 's/\([a-zA-Z0-9_]*=\)"\([^"]*\)"/\1'\''\2'\''/g' followed by inspecting the results, and touching up the change in tests/xml2sexprdata/xml2sexpr-escape.xml to fix 'make check'. * cfg.mk (sc_rng_quote_style): Enforce the rule. * examples/xml/storage/*.xml: Fix fallout. * examples/xml/test/*.xml: Likewise. * python/libvirt-*override-api.xml: Likewise. * src/network/default.xml: Likewise. * tests/*/*.xml: Likewise.
