[Vtd-xml-users] Weird edge case with element fragment and PI

[Owen, S. S. U. <sam...@sp...>]

??Hi,


I've come across what I believe is a bug when processing instructions are included. Here's a test case.


Thanks,

Sam

import com.ximpleware.*;
import org.junit.Assert;
import org.junit.Test;


public class PIBugTest {

    @Test
    public void getElementFragmentTooLongWhenPIAndCarrageReturn() throws XPathParseException, NavException, XPathEvalException, ParseException {
        String exampleXml =
                "<a>\n" +
                        " <b>value</b>\n" +
                        " hello\n" +
                        " <?pi inst $pi#?>\n" +
                        " <b>another value</b>\n" +
                        "</a>\n";

        VTDGen vg = new VTDGen();
        vg.setDoc(exampleXml.getBytes());
        vg.parse(false);

        VTDNav nav = vg.getNav();

        AutoPilot autoPilot = new AutoPilot(nav);
        autoPilot.selectXPath("/a//b");
        autoPilot.evalXPath();

        long fragment = nav.getElementFragment();
        IByteBuffer xml = nav.getXML();

        int offset = (int) fragment;
        int len = (int) (fragment >>> 32);

        //Fix for weird bug with pi
        Assert.assertEquals(new String(xml.getBytes(), offset, len), "<b>value</b>");
    }
}
?
