How to calculate Digest Value in SOAP/XML?

After searching over internet, I have tried to generate digest value using following two methods:

shasum filename.txt | cut -f 1 -d ' ' | xxd -r -p | base64
openssl dgst -binary filename.txt | openssl enc -base64

I have used “SignatureValue” to create digest value, but shows incorrect value. My doubt is, which value of this SOAP/XML message would be used to calculate digest value? and any problem in my digest value calculation method??.

Below is my SOAP/XML message,
