310478 - E4X handles whitespace in text incorrectly

Status: RESOLVED INVALID

(Core :: JavaScript Engine, defect)

Description

[conor]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.9a1) Gecko/20050926 Firefox/1.6a1

10.1 of the ECMA spec says that toXMLString should strip leading
and trailing spaces from a text node iff prettyPrint is true. This test shows
that the Mozilla E4X always strips spaces from some text nodes irrespective of
the prettyPrint setting.

Reproducible: Always

Steps to Reproduce:
	var textAfterSpan = "<p><span> A sentence with a leading </span> and then one
with another leading space.</p>";
	var xmlText = new XML(textAfterSpan);
	XML.prettyPrinting = false;
	var spanText = xmlText.children()[0].toXMLString();
	var followingText = xmlText.children()[1].toXMLString();
	XML.prettyPrinting = true;
	var spanTextPretty = xmlText.children()[0].toXMLString();
	var followingTextPretty = xmlText.children()[1].toXMLString();

	// All ok: whitespace is preserved in spanText so it isn't the same as 
	// its "pretty" equivalent
	if(spanText == spanTextPretty)
		alert("Got bug: problem with whitespace in text inside embedded tags");

	// Bug: leading whitespace removed no matter what
	if(followingText == followingTextPretty)
		alert("Got bug: problem with whitespace in text following an embedded tag");

You need to set XML.ignoreWhitespace = false; in addition to clearing
XML.prettyPrinting to see whitespace preserved from input to toXMLString output.
