Hi all guys,
One thing I've always found a little "annoying" - "boring" is maybe
the more appropriate therm - of SAX APIs is that, when crating even
simple XML snippets via ContentHandler APIs, the following boilerplate
code has to be written:
+--------+
ContentHandler handler = ... ;
contentHandler.startDocument();
contentHandler.startElement( "", "project", "project", new AttributesImpl() );
contentHandler.startElement( "", "modelVersion", "modelVersion", new
AttributesImpl() );
String modelVersion = "4.0.0";
contentHandler.characters( modelVersion.toCharArray(), 0,
modelVersion.length() );
contentHandler.endElement( "", "modelVersion", "modelVersion" );
contentHandler.endElement( "", "project", "project", new AttributesImpl() );
contentHandler.endDocument();
+--------+
I think you would agree with me that to obtain the following snippet
+--------+
<?xml version="1.0" encoding="UTF-8"?>
<project>
<modelVersion>4.0.0</modelVersion>
</project>
+--------+
that code is maybe an overkill :P
So, at company I developed a small SAX wrapper that would help on
transforming the previous code in the following:
+--------+
ContentHandler handler = ... ;
SAXEventsBuilder.newDocument( transformerHandler )
.start( "project" )
.start( "modelVersion" ).body( "4.0.0" ).end()
.end()
.endDocument();
+--------+
isn't more "sexy"? It still supports elements that require
namespaces/attributes but reduces the lines of code for hardcoded XML
documents - especially when closing elements.
It also allows users to add manually-generated elements in an existing
ContentHandler:
+--------+
ContentHandler handler = ... ;
SAXEventsBuilder.wrap( transformerHandler )
.start( "modelVersion" ).body( "4.0.0" ).end()
.start( "groupId" ).body( "org.apache.cocoon.sax" ).end()
.start( "artifactId" ).body( "cocoon-sax" ).end()
.start( "version" ).body( "3.0.0-beta-1" ).end()
+--------+
without starting/closing the document.
If you like it, I would be pleased to commit it in the Cocoon repo -
as a side question: which component that would fill?
Many thanks in advance, all the best!
