can we get a signature element without linefeeds using apache xml security 1.4.1 ?

[ragunath Mariappan]

Hi all!

I created an XML Signature element, using apache xml-security-1_4_1 API as below :

XMLSignature sig = new XMLSignature (DomNode,"",XMLSignature.ALGO_ID_SIGNATURE_RSA_SHA1);

which created a signature element as below (with line-feeds),

<ds:Signature xmlns:ds="http://www.w3.org/2000/09/xmldsig#">
<ds:SignedInfo>
<ds:CanonicalizationMethod Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#"/>

I would like to know how a signature element without a linefeed could be generated as above using the apache XML xml-security-1_4_1 API.

Could anyone help me with this.

Thanks,

Hello
I don't have an answer for you, but I'm curious, why do you care about line feeds in your XML?
