Insert XML into existing XML by calling InsertChildTreeAfter

See more XML Examples

Demonstrates how to insert an XML tree or subtree into another XML document using the InsertChildTreeAfter method. Visual FoxPro

LOCAL loXml
LOCAL loXml2
LOCAL lnIndex

* Build the 1st XML document:
* <x1>
*     <a1>1</a1>
*     <a2>2</a2>
*     <a3>3</a3>
* </x1>

loXml = CreateObject('Chilkat.Xml')
loXml.Tag = "x1"
loXml.UpdateChildContent("a1","1")
loXml.UpdateChildContent("a2","2")
loXml.UpdateChildContent("a3","3")

* Build a 2nd XML document:

* <x2>
*   <b1>11</b1>
*   <b2>22</b2>
*   <b3>33</b3>
* </x2>

loXml2 = CreateObject('Chilkat.Xml')
loXml2.Tag = "x2"
loXml2.UpdateChildContent("b1","11")
loXml2.UpdateChildContent("b2","22")
loXml2.UpdateChildContent("b3","33")

* We want to insert xml2 into xml to get this:

* <x1>
*     <a1>1</a1>
*     <x2>
*         <b1>11</b1>
*         <b2>22</b2>
*         <b3>33</b3>
*     </x2>
*     <a2>2</a2>
*     <a3>3</a3>
* </x1>

* Insert xml2 after "a1"

lnIndex = loXml.TagIndex("a1")
IF (lnIndex < 0) THEN
    ? "a1 not found."
    RELEASE loXml
    RELEASE loXml2
    CANCEL
ENDIF

loXml.InsertChildTreeAfter(lnIndex,loXml2)

? loXml.GetXml()

* The result is:

* <x1>
*     <a1>1</a1>
*     <x2>
*         <b1>11</b1>
*         <b2>22</b2>
*         <b3>33</b3>
*     </x2>
*     <a2>2</a2>
*     <a3>3</a3>
* </x1>

* Note: xml2 now points to the subtree within xml.
* For example, update "b3" and then see how it's updated within the merged document:
loXml2.UpdateChildContent("b3","33333333")

? loXml.GetXml()

* The result:

* <x1>
*     <a1>1</a1>
*     <x2>
*         <b1>11</b1>
*         <b2>22</b2>
*         <b3>33333333</b3>
*     </x2>
*     <a2>2</a2>
*     <a3>3</a3>
* </x1>
