java - check the compatibility of an XML document against a DTD using JDOM? -

-

i working java , want check if xml file valid against dtd.

assuming have dtd file, want check if xml file valid against same definitions proposed in dtd file.

is there way using jdom?

yes, can, in jdom. it's easiest in jdom 2.x (as opposed 1.x).

see the saxbuilder constructor takes xmlreaderjdomfactory. example usage is:

    saxbuilder sb = new saxbuilder(xmlreaders.dtdvalidating);     document doc = sb.build("http://www.w3schools.com/dtd/note_ex_dtd.xml");     xmloutputter xout = new xmloutputter(format.getprettyformat());     xout.output(doc, system.out);

note above code validated xml against dtd specified in doctype declaration ("note.dtd") @ location relative note-ex_dtd.xml document.

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
