DigestValue of the xml document in php -

could please me how accomplish correct digestvalue in xml document? have xml examples creator, somehow cannot generate same sha256 hash in php.

the documentation says <soap:body> should hashed using sha256 algorithm. well, understand need to

1. canonicalize xml (c14n)
2. create sha256 hash it
3. base64 encode it

the hash result example should twpslqpoxsue8k6q8lad7dymhwkticbhnifrpnwdg/m=

how accomplish in php code below?

i tried this:

but returning me other hash value :-( maybe taking wrong part of xml source. ideas part of text/how did count hash , how have same result in php? whole working example (taken [http://www.etrzby.cz/assets/cs/prilohy/cz1212121218.valid.v3.1.xml) this:
