c++ - TinyXPath not filtering the required dom element according to the given attribute query? -

-

example xml is:

  <dgn>       <sg>         <nodes>           <node name="sphere 1" clsid="{cf21f965-203a-456a-83fe-a5f62d6d8e50}" type="mesh" id="{418acdd5-65d2-410f-b43b-0b48e4010b75}" subtype="" version="2.0" cloneparentkey="" nextcloneparentkey="">             <object id="{ac685ad2-3411-43b0-a29b-3b22086baef6}">sphere 1</object>             <material id="{d2029f35-4a85-4669-bbf3-e754568ed88c}">standard 1</material>             <controllers>               <controller id="{989803fd-b575-45e4-b8a0-b5e69008145b}" weight="100" name="default" inherit="-1">                 <tracks>                   <track name="radius" type="parametric" numkey="0" pathfollow="0">                     <interpolator clsid="{ecc9c2c7-5175-4784-9108-1fa4c25d3383}" type="float">                       <key frame="-1">75.000000,0.000000,0.000000,0.000000</key>                     </interpolator>                   </track>                   </track>                   <track name="scale" type="srtv" numkey="101" pathfollow="0">                     <interpolator clsid="{ecc9c2c7-5175-4784-9108-1fa4c25d3383}" type="float3">                       <key frame="-1">1.000000,1.000000,1.000000,1.000000</key>                     </interpolator>                   </track>                   <track name="rotation" type="srtv" numkey="102" pathfollow="0">                     <interpolator clsid="{ecc9c2c7-5175-4784-9108-1fa4c25d3383}" type="float3">                       <key frame="-1">0.000000,0.000000,0.000000,0.000000</key>                     </interpolator>                   </track>                  </tracks>               </controller>             </controllers>             <customdata>               <offsetmatrix>1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,1</offsetmatrix>               <poslinkvector>0.000000,0.000000,0.000000,0.000000</poslinkvector>             </customdata>           </node>           <node name="circle 1" clsid="{cf21f965-203a-456a-83fe-a5f62d6d8e50}" type="shape" id="{418acdd5-65d2-410f-b43b-0b48e4010b75}" subtype="" version="2.0" cloneparentkey="" nextcloneparentkey="">             <object id="{ac685ad2-3411-43b0-a29b-3b22086baef6}">sphere 1</object>             <material id="{d2029f35-4a85-4669-bbf3-e754568ed88c}">standard 1</material>             <controllers>               <controller id="{989803fd-b575-45e4-b8a0-b5e69008145b}" weight="100" name="default" inherit="-1">                 <tracks>                   <track name="radius" type="parametric" numkey="0" pathfollow="0">                     <interpolator clsid="{ecc9c2c7-5175-4784-9108-1fa4c25d3383}" type="float">                       <key frame="-1">75.000000,0.000000,0.000000,0.000000</key>                     </interpolator>                   </track>                   </track>                   <track name="scale" type="srtv" numkey="101" pathfollow="0">                     <interpolator clsid="{ecc9c2c7-5175-4784-9108-1fa4c25d3383}" type="float3">                       <key frame="-1">1.000000,1.000000,1.000000,1.000000</key>                     </interpolator>                   </track>                   <track name="rotation" type="srtv" numkey="102" pathfollow="0">                     <interpolator clsid="{ecc9c2c7-5175-4784-9108-1fa4c25d3383}" type="float3">                       <key frame="-1">0.000000,0.000000,0.000000,0.000000</key>                     </interpolator>                   </track>                  </tracks>               </controller>             </controllers>             <customdata>               <offsetmatrix>1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,1</offsetmatrix>               <poslinkvector>0.000000,0.000000,0.000000,0.000000</poslinkvector>             </customdata>           </node>         </nodes>       </sg>     </dgn>

when query contains xpath "dgn/sg/nodes/node[@type='mesh']" should give me onle 1 node selects both nodes(sphere 1 , circle 1). not happens if change dom element name "node" else in xml i.e. if rename "node" "abc" , query xpath "dgn/sg/nodes/abc[@type='mesh']" filters desired dom element i.e. gives sphere 1. not happen dom element name other "node". node keyword in tinyxpath or else???

why happens dom element named "node"????

actionscript 3 - TweenLite does not work with object -

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
