Hi All, I will appreciate if somebody could help on how to normalize and canonicalize XML.
For example <?xml version="1.0" encoding="WINDOWS-1251"?> <ed:N1 attr="4583001999" xmlns:ed="urn:ru:ed:v2.0"> </ed:N> I need to get <n1:N1 xmlns:n1="urn:cbr-ru:ed:v2.0" attr="4583001999"></n1:N1> And for <?xml version="1.0" encoding="WINDOWS-1251"?> <N1 attr="4583001999" xmlns="urn:ru:ed:v2.0"> <N2 attr="value"></N2> </N1> I need <n1:N1 xmlns:n1="urn:ru:ed:v2.0"> attr="4583001999"<n1:N2 attr="value"></n1:N2></n1:N1> In other words I need to remove whitespaces and rewrite namespace prefixes I use string src; xmlChar * canon; xmlDocPtr xDoc = xmlReadMemory(src.data(), src.size(), nullptr, nullptr, XML_PARSE_NOBLANKS); int bytes = xmlC14NDocDumpMemory(xDoc, nullptr, 0, nullptr, 0, & canon); It removes whitespaces, need help with namespace prefix rewrite. Thank you in advance.
