Re: [xml] Need help on normalization/canonicalization with namespace prefix rewrite

2018-01-30 Thread Mikhail Goloborodko 
Hi Alexey,

I'm trying to get canonicalized xml (not according to standard) text to
sign it.
I need to rewrite namespace prefixes for that.
I modified c14n.c to meet my certain requirements - it is suitable for my
particular rules.
I included examples of xml i need in my previous emails.
So I hardcoded my namespace prefixes so it works for this case.
Would appretiate if somebody advise on how to achive that with no code
change.

Regards,
Mikhail

I don't understand what are you trying to do so I really don't have
a good answer for you.

Alexey,

Thank you!
I'am new to libxml2. Would appretiate if you advice how to achieve this.
May be I need a callback for in Reader or Writer?

Re: [xml] Need help on normalization/canonicalization with namespace prefix rewrite

2018-01-28 Thread Aleksey Sanin 
I am not sure what is the suggest algorithm to "rewrite namespace
prefixes". Regardless, this is not part of C14N spec and something
you will have to do yourself.

[xml] Need help on normalization/canonicalization with namespace prefix rewrite

2018-01-28 Thread Mikhail Goloborodko 
Hi All,

I will appreciate if somebody could help on how to normalize and
canonicalize XML.

For example




I need to get



And for



  


I need

 attr="4583001999"

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.
