麻烦insertChildAfter对XML的actionsctipt 3 [英] Trouble with insertChildAfter for xml in actionsctipt 3
问题描述
我有一个很大的麻烦，非常嵌套在我的XML的现有节点之后插入一个孩子。我试图插入下方object3_LIST3另一个IObject节点。
我试过相同的方案<一href="http://stackoverflow.com/questions/189033/having-trouble-with-insertchildbefore-and-insertchildafter-in-as3">having在AS3 这一带insertChildBefore和insertChildAfter麻烦。这始终输出不定，我似乎无法弄清楚为什么..谁能帮助？
如果我跟踪contentNode和parentNode，它输出：
object3_LIST3
和
＆LT;对象＆GT;
＆LT; IObject＆GT; object3_LIST3＆LT; / IObject＆GT;
＆LT; /对象＆GT;
好像没有变化都对文档所作的...
VAR contentNode：XML = xml.Menu.menuArr.HeadMenuItem [1] .subMenu.subMenuItem [1] .objects [0];
变种parentNode：XML = xml.Menu.menuArr.HeadMenuItem [1] .subMenu.subMenuItem [1] .objects.IObject [0];
XML = parentNode.insertChildAfter（contentNode，的xmlString）;
跟踪（XML）;
＆LT; PandemicMenu＆GT;
＆LT;菜单＆gt;
＆LT; menuArr＆GT;
＆LT; HeadMenuItem＆GT;
＆LT;子＆GT;
＆LT; IObject＆GT;
object1_LIST1
＆LT; / IObject＆GT;
＆LT; IObject＆GT;
object2_LIST1
＆LT; / IObject＆GT;
＆LT; IObject＆GT;
object3_LIST1
＆LT; / IObject＆GT;
＆LT; /子菜单＆GT;
＆LT; / HeadMenuItem＆GT;
＆LT; HeadMenuItem＆GT;
＆LT;子＆GT;
＆LT; IObject＆GT;
object1_LIST2
＆LT; / IObject＆GT;
＆LT; subMenuItem＆GT;
＆LT;对象＆GT;
＆LT; IObject＆GT;
object2_LIST2
＆LT; / IObject＆GT;
＆LT; /对象＆GT;
＆LT; / subMenuItem＆GT;
＆LT; subMenuItem＆GT;
＆LT;对象＆GT;
＆LT; IObject＆GT;
object3_LIST3
＆LT; / IObject＆GT;
想在这里插入新IObject
＆LT; /对象＆GT;
＆LT; / subMenuItem＆GT;
＆LT; /子菜单＆GT;
＆LT; / HeadMenuItem＆GT;
＆LT; / menuArr＆GT;
＆LT; /菜单＆gt;
＆LT; / PandemicMenu＆GT;
您的父节点和子节点切换。你的孩子节点是：
VAR contentNode：XML = xml.Menu.menuArr.HeadMenuItem [1] .subMenu.subMenuItem [1] .objects [0];
这将跟踪具有以下一个 contentNode.toXMLString（）：
＆LT;对象＆GT;
＆LT; IObject＆GT; object3_LIST3＆LT; / IObject＆GT;
＆LT; /对象＆GT;
由于文档状态：如果提供child1，但它不能在XML对象存在，XML对象不修改并返回undefined。的http://www.adobe.com/livedocs/flash/9.0/ActionScriptLangRefV3/XML.html#insertChildAfter%28%29
这个问题可能是你要求的子节点查找其父节点，它无法找到，因此原来是不变。请尝试以下操作：
VAR parentNode：XML = xml.Menu.menuArr.HeadMenuItem [1] .subMenu.subMenuItem [1] .objects [0];
变种contentNode：XML = xml.Menu.menuArr.HeadMenuItem [1] .subMenu.subMenuItem [1] .objects.IObject [0];
XML = parentNode.insertChildAfter（contentNode，的xmlString）;
跟踪（XML）;
我所做的只是切换parentNode和contentNode XML对象的内容。
I'm having a lot of trouble with inserting a child after an existing node that is VERY nested in my XML. I'm trying to insert another IObject node beneath object3_LIST3.
I've tried the same scheme as having trouble with insertChildBefore and insertChildAfter in AS3 with this. This always outputs undefined and I can't seem to figure out why.. Can anyone help?
If I trace contentNode and parentNode, it outputs:
object3_LIST3
and
<objects>
<IObject>object3_LIST3</IObject>
</objects>
As if no changes were made at all to the document...
var contentNode:XML = xml.Menu.menuArr.HeadMenuItem[1].subMenu.subMenuItem[1].objects[0];
var parentNode:XML = xml.Menu.menuArr.HeadMenuItem[1].subMenu.subMenuItem[1].objects.IObject[0];
xml = parentNode.insertChildAfter( contentNode, xmlString );
trace(xml);
<PandemicMenu>
<Menu>
<menuArr>
<HeadMenuItem>
<subMenu>
<IObject>
object1_LIST1
</IObject>
<IObject>
object2_LIST1
</IObject>
<IObject>
object3_LIST1
</IObject>
</subMenu>
</HeadMenuItem>
<HeadMenuItem>
<subMenu>
<IObject>
object1_LIST2
</IObject>
<subMenuItem>
<objects>
<IObject>
object2_LIST2
</IObject>
</objects>
</subMenuItem>
<subMenuItem>
<objects>
<IObject>
object3_LIST3
</IObject>
Want to insert new IObject here
</objects>
</subMenuItem>
</subMenu>
</HeadMenuItem>
</menuArr>
</Menu>
</PandemicMenu>
Your parent node and child nodes are switched. You child node is:
var contentNode:XML = xml.Menu.menuArr.HeadMenuItem[1].subMenu.subMenuItem[1].objects[0];
Which would trace the following with a contentNode.toXMLString():
<objects>
<IObject>object3_LIST3</IObject>
</objects>
Since the docs state: "If child1 is provided, but it does not exist in the XML object, the XML object is not modified and undefined is returned." http://www.adobe.com/livedocs/flash/9.0/ActionScriptLangRefV3/XML.html#insertChildAfter%28%29
The problem could be that you are asking the child node to look for its parent node, which it can't find, and so the original is unmodified. Try the following:
var parentNode:XML = xml.Menu.menuArr.HeadMenuItem[1].subMenu.subMenuItem[1].objects[0];
var contentNode:XML = xml.Menu.menuArr.HeadMenuItem[1].subMenu.subMenuItem[1].objects.IObject[0];
xml = parentNode.insertChildAfter( contentNode, xmlString );
trace(xml);
All I did was switch the content of the parentNode and contentNode XML objects.
