Re: [Pharo-users] XML Writer not pretty printing

Aug. 14, 2018

      Hi Peter

It seems that #preservesIgnorableWhitespace: is only adhered to "...When validation is enabled and a DTD with element declarations is present..." (See comment in SAX2ContentHandler>>ignorableWhitespace:) The actual parsing code is in SAXParserDriver>>handleWhitespace:

What you could do is use #removeAllFormattingNodes but your-mileage-may-vary...

parser := XMLDOMParser
	on:'<root>
	<tab/>
  <twoSpaces/>
    <fourSpaces/>
</root>'.

(parser parseDocument)
	removeAllFormattingNodes;
	prettyPrinted.

Regards
Carlo

Hi,

I am trying to output a pretty printed document, but it seems that the configuration is being ignored

doc := '<root>
	<tab/>
  <twoSpaces/>
    <fourSpaces/>
</root>' parseXML.

String << [ :stream |
	doc	
		printOn: stream
		beforeWritingDo: [ :writer | 
			writer
				enablePrettyPrinting;
				enablePlatformSpecificLineBreak.
			writer formatter indentString: '  '. ] ]

produces

 "'<root>
	<tab/>
  <twoSpaces/>
    <fourSpaces/>
</root>'"

I thought that maybe #preservesIgnorableWhitespace: has something to do with it, but whether it is true or false, the output is not pretty printed (not to mention, that pretty printing should ignore any preserved whitespaces anyway).

Is this a bug? Should I print it in a different way?

Thanks,
Peter
