Hey guys, I'm converting a bit of codes so it loads easily in XML using BlitzXML, it going good. What I want to do, is to load and animate a model, so in my test xml I have the following: <?xml version="1.0"?> <map> <info> <title>Character</title> <author>NRasool</author> <description>An XML file which holds the actors</description> </info> <world> <entity type="actor"> <role type="Hero"> <filename>../hero/hero.b3d</filename> <NoOfAnim>17</NoOfAnim> <AnimSequence StartFrame="2" EndFrame="16"/> <AnimSequence StartFrame="18" EndFrame="32"/> <AnimSequence StartFrame="34" EndFrame="52"/> <AnimSequence StartFrame="55" EndFrame="78"/> <AnimSequence StartFrame="80" EndFrame="94"/> <AnimSequence StartFrame="97" EndFrame="113"/> <AnimSequence StartFrame="116" EndFrame="134"/> <AnimSequence StartFrame="136" EndFrame="151"/> <AnimSequence StartFrame="152" EndFrame="172"/> <AnimSequence StartFrame="173" EndFrame="188"/> <AnimSequence StartFrame="189" EndFrame="201"/> <AnimSequence StartFrame="202" EndFrame="213"/> <AnimSequence StartFrame="214" EndFrame="222"/> <AnimSequence StartFrame="223" EndFrame="240"/> <AnimSequence StartFrame="244" EndFrame="271"/> <AnimSequence StartFrame="242" EndFrame="320"/> <AnimSequence StartFrame="322" EndFrame="336"/> </role> </entity> </world> </map> Now the issue is in my blitz coding, how would I go to the role for the actor. I thought about putting another for loop eg using xmlnodechild, but the logic is not getting right, please could someone just give a friendly advise, I don't want you to do all the coding, just a heads up really ;Create entities founder under the world node worldnode = xmlNodeFind("world", rootnode) ;Get the handle of the world node count = xmlNodeChildCount(worldnode) ;Get the world node's child count For i = 1 To count ;Loop through each child node of the world node entitynode = xmlNodeChild(worldnode, i) ;Get the child node If xmlNodeNameGet(entitynode) = "entity" Then ;Check if it's an entity t$ = xmlNodeAttributeValueGet(entitynode, "type") ;Get the entity type End If ; Now lets start loading in Actors If t = "actor" Then ; ------------------------> What should I put in here EndIf Next

Hey there, Just to add into this, My issue is that to I gone into the Actor Type, but how do I drill down to the Role Type, then Hero type. Would you put another recursive for loop for it to drill down, or would there be an easier way. I have been looking through you help file and tried to use xmlNodeChild("role", "hero"), but it is not picking it up when I check through debug Please could anyone give me a stepping stone to this. Kind Regards

Never mind with this, I've cracked it now, here is my fixed coding worldnode = xmlNodeFind("world", rootnode) ;Get the handle of the world node DebugLog "World Count:" + worldnode count = xmlNodeChildCount(worldnode) ;Get the world node's child count For i = 1 To count ;Loop through each child node of the world node entitynode = xmlNodeChild(worldnode, i) ;Get the child node DebugLog "Worldnode Child Count:" + entitynode If xmlNodeNameGet(entitynode) = "entity" Then ;Check if it's an entity t$ = xmlNodeAttributeValueGet(entitynode, "type") ;Get the entity type DebugLog "Level Node: " + xmlnodelevel(entitynode) End If ; Now lets start loading in Actors If t = "actor" Then actor_count = xmlNodeChildCount(entitynode) DebugLog "How many Actors are there:" + actor_count For actor_count_range = 1 To actor_count actor_entitynode = xmlNodeChild(entitynode, actor_count_range) If xmlNodeNameGet(actor_entitynode) = "role" Then role_type$ = xmlNodeAttributeValueGet(actor_entitynode, "type") ;Get the entity type End If If role_type = "Hero" Then End ; This is just to test Next EndIf Next This works for me, its nice after a weekend off, I can now see clearly
