Scott Cantor commented on XERCESC-2025:
---------------------------------------
I'll take a look, but that isn't how I interpret that code at all. The clause
there is dumping the declaration conditionally, and then dumping the *document*
node, i.e. the whole thing we're serializing. The printNewLine there is at the
end of that, not before it.
> Empty line generated when fgDOMXMLDeclaration is disabled

> Key: XERCESC-2025
> URL: https://issues.apache.org/jira/browse/XERCESC-2025
> Project: Xerces-C++
> Issue Type: Bug
> Components: DOM
> Affects Versions: 3.1.0, 3.1.1, 3.1.2, 3.1.3, 3.1.4
> Reporter: Jose M. Sanchez
> Assignee: Scott Cantor
> Priority: Minor
> Labels: DOMLSSerializer, empty, line
> Fix For: 3.2.0
>
>
> The DOMLSSerializer implementation is generating a leading empty line
> in case that the generation of the XML Declaration is disabled.
> The source code looks like this:
> https://svn.apache.org/repos/asf/xerces/c/trunk/src/xercesc/dom/impl/DOMLSSerializerImpl.cpp
> if (getFeature(XML_DECLARATION)) {
> // use the version and encoding resolved
> *fFormatter << gXMLDecl_VersionInfo << fDocumentVersion <<
> gXMLDecl_separator;
> *fFormatter << gXMLDecl_EncodingDecl << fEncodingUsed <<
> gXMLDecl_separator;
> const XMLCh* st = (docu->getXmlStandalone())?
> XMLUni::fgYesString : XMLUni::fgNoString;
> *fFormatter << gXMLDecl_SDDecl << st << gXMLDecl_separator;
> *fFormatter << gXMLDecl_endtag;
> }
> DOMNodeSPtr child = nodeToWrite->getFirstChild();
> while( child != 0)
> {
> processNode(child, level);
> child = child->getNextSibling();
> }
> printNewLine();
> The printNewLine() method is called even if no XML declaration was written,
> thus generating a leading empty line.
