Re: [Vtd-xml-users] VTDNav.getText() issue?

Yes, it is a change of behavior in the latest version, it is not
supposed to return -1, it should return a text node of zero width, you
should adjust your app accordingly...

Subject:[Vtd-xml-users] VTDNav.getText() issue?

Previously, actually very old version, we use VTDNav.getText() [1] to
determine whether we have some text value, if not we get the whole
element for further processing, e.g. 1) "" with xpath "/root/e1" will
yield "";2) "aaa" with xpath "/root/e1" will yield "aaa".
Basically, we use selecXPath(xpath) and evalXPath(), then if
VTDNav.getText() [2] return -1, we grab the whole element; otherwise,
we use vtdNav.toNormalizedString(vtdNav.getText() [3] to get the text
value.
However, in the current version of VTD, when we use the
vtdNav.getText() [4] on above two examples, we get number 3 for both
cases. However, we'd expect -1 for the case #1 and 3 for case #2.
Really appreciate if somebody could help promptly address this
issue.
