I think you're probably out of luck - the method was de-COMed, and is now not accessible from external C++ code.
In generally, using nsIDOM* interfaces from external applications is explicitly not supported. If you want to do DOM stuff, you should do so from JS, and communicate with your JS code using a JS-implemented XPCOM component. bholley On Sat, Nov 1, 2014 at 10:52 AM, <fuller...@gmail.com> wrote: > 在 2014年11月1日星期六UTC+8下午4时40分57秒，David Rajchenbach-Teller写道： > > I believe that the methods have migrated to > > > http://dxr.mozilla.org/mozilla-central/source/dom/xslt/xpath/XPathResult.h?from=XPathResult#47 > > > > Cheers, > > David > > > > On 01/11/14 08:43, fuller...@gmail.com wrote: > > > Hi, > > > > > > Xulrunner 33.x is different from the former releases.
