Note that this behavior is required by the XML specification. See http://www.w3.org/TR/2008/REC-xml-20081126/#AVNormalize. It's dense, but in summary, when an attribute value is loaded, leading and trailing white space is discarded, and each sequence of spaces, tabs, carriage returns, and linefeeds are converted to a single space.
This applies only if there's no schema indicating that the attribute value is CDATA, but the safest thing for a serializer to do is assume that the value might not be CDATA (or might not be recognized as such by whatever processor loads the document) and that whitespace should be preserved. The only way to guarantee that is to write the whitespace characters as entities. -----Original Message----- From: Alberto Massari [mailto:[email protected]] Sent: Thu 7/30/2009 11:37 AM To: [email protected] Subject: Re: DOMLSSerializer converts white space characters in attributes to xml entities No, if the serialized attribute value has newlines/tab, they are converted upon loading into spaces. If you want to really store such characters in an attribute, they have to be encoded into entities.
