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;
 

解决方案

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.
