java - XML Parsing problems getting #text in nodeList -


i'm writing xml parser parse documents this:

<?xml version="1.0"?> <world x="1920" y="1080">     <samples>2</samples>     <camera>         <origin x="0.0" y="50.0" z="-600.0"></origin>         <direction x= "0.0" y = "0.0" z = "0.0"></direction>         <fov>30</fov>     </camera>     <objects>         <plane>             <shader>lambertian</shader>             <colour r="1.0" g="1.0" b="1.0"></colour>             <origin x="0.0" y="-80.0" z="0.0"></origin>             <normal x="0.0" y="-1.0" z="0.0"></normal>         </plane>         <sphere>             <shader>lambertian</shader>             <colour r="0.0" g="1.0" b="0.0"></colour>             <origin x="-100.0" y="-40.0" z="-200.0"></origin>             <radius>40</radius>         </sphere>         <sphere>             <shader>reflective</shader>             <origin x="0.0" y="-40.0" z="-200.0"></origin>             <radius>40</radius>         </sphere>         <sphere>             <shader>transparent</shader>             <origin x="-40.0" y="-40.0" z="-300.0"></origin>             <radius>40</radius>             <ri>1.07</ri>         </sphere>     </objects>     <lights>         <light>             <origin x="100.0" y="200.0" z="-300.0"></origin>             <colour r="1.0" g="1.0" b="1.0"></colour>         </light>         <light>             <origin x="-100.0" y="300.0" z="-400.0"></origin>             <colour r="0.5" g="0.5" b="0.5">origin</colour>         </light>     </lights> </world>

however i'm having trouble code parsing far is:

file inputfile = new file(filename); documentbuilderfactory dbfactory = documentbuilderfactory.newinstance();  documentbuilder dbuilder = dbfactory.newdocumentbuilder();  document doc = dbuilder.parse(inputfile);  doc.getdocumentelement().normalize();  element rootele = doc.getdocumentelement();  string resx = rootele.getattribute("x"); string resy = rootele.getattribute("y");  int width = integer.parseint(resx); int height = integer.parseint(resy);  raytracer.setworld(width, height);  nodelist nodes = rootele.getchildnodes();  system.out.println(nodes.item(0).getnodename());  node sampler = nodes.item(1);  string samplestemp = sampler.gettextcontent();  system.out.println(samplestemp);  int samples = integer.parseint(samplestemp);  raytracer.setsampler(samples);  node camera = nodes.item(2);

but i'm getting weird results, instance in system.out.println(nodes.item(0).getnodename()); got #text , i'm not sure comes from. item(1) samples, item(2) #text , item(3) camera.

if xml formatted in example, e.g.

<world x="1920" y="1080">     <samples>2</samples>     .... </world>

then there #text between start tag <world> , start tag samples. in case there line break , 4 whitespaces. first node after <world>.

perhaps want ignore whitespaces.
