consecutive spaces in xml text value are collapsed into a single one

[amnonkhen]

The 2 spaces in the value of the a element in x y are squashed into a single space.

@Test
public void test_multiple_spaces() throws ParseException, XPathParseException, NavException, XPathEvalException {
    VTDGen vtdGen = new VTDGen();
    // notice the 2 spaces
    String expectedValue = "x  y";
    vtdGen.setDoc(("<a>" + expectedValue + "</a>").getBytes());
    vtdGen.parse(true);  // set namespace awareness to true
    VTDNav vn = vtdGen.getNav();
    AutoPilot ap = new AutoPilot(vn);
    ap.selectXPath("//a");
    String actualValue = null;
    int result = -1;
    result = ap.evalXPath();
    if (result != -1) {
        int t = vn.getText();
        if (t != -1)
            actualValue =  vn.toNormalizedString(t);
    }
    Assert.assertEquals(expectedValue, actualValue);
}

The code for reading the value using xpath is taken from the code samples page

I just saw in the javadoc of toNormalizedString that space collapsing is the intended behavior.
I realized that using toNormalizedString2 instead of toNormalizedString the bug does not happen.
What is the difference between the two?

toString is the one you should consider using if you don't want collapsed space... toRawString would even conserve character/built-in entities...
