Specifically, catalog.c in libxml2 has this:

            /* the XML_CATALOG_FILES envvar is allowed to contain a
               space-separated list of entries. */
            cur = catalogs;
            nextent = &catal->xml;
            while (*cur != '\0') {
                while (xmlIsBlank_ch(*cur))
                    cur++;
