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

[Carlo]

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
