i have an xml doc that looks like this

<?xml version="1.0" encoding="UTF-8"?>
<messageList>
      <message>

          <sender>john</sender>

          <forPage>home</forPage>
     </message>

</messagelist>

i want to add another element called <forPage> under the current one.(one to many relationship). my code below overwrite the first entered <forPage>

   <cfset arrayInsertAt(xApps.messageList.xmlChildren,1,xmlElemNew(xApps,'message'))>
   <cfset xApps.messageList.message[1].sender = xmlElemNew(xApps,'sender')>
   <cfset xApps.messageList.message[1].sender.xmlText = "john">

   <cfset xApps.messageList.message[1].forPage  = xmlElemNew(xApps,'forPage')>
   <cfset xApps.messageList.message[1].forPage.xmlText = "home">   
   <cfset xApps.messageList.message[1].forPage = xmlElemNew(xApps,'forPage')>
   <cfset xApps.messageList.message[1].forPage.xmlText= "sales">

i am looking to update my xml like this

<?xml version="1.0" encoding="UTF-8"?>
<messageList>
      <message>

          <sender>john</sender>

          <forPage>home</forPage>

          <forPage>sale</forPage>

     </message>

</messagelist>

this code will eventually be put into a loop to account for numerous occurrences of <forpage>.

thanks for your time

If you want multiple forPage elements you need to treat it like an array just like you did earlier to add a message element to the xmlChildren array of message list.


Here is a example hardcoded to just add two forPage elements.  You would probably need to incorporate other array functions to modify this for a loop such as arrayLen().

<cfset arrayInsertAt(xApps.messageList.xmlChildren,1,xmlElemNew(xApps,'message'))>
<cfset xApps.messageList.message[1].sender = xmlElemNew(xApps,'sender')>
<cfset xApps.messageList.message[1].sender.xmlText = "john">

<cfset arrayAppend(xApps.messageList.message[1].xmlChildren,xmlElemNew(xApps,'forPage'))>
<cfset xApps.messageList.message[1].forPage[1].xmlText = "home">

<cfset arrayAppend(xApps.messageList.message[1].xmlChildren,xmlElemNew(xApps,'forPage'))>
<cfset xApps.messageList.message[1].forPage[2].xmlText= "sales">

you are correct. i was trying it like this

<cfset arrayInsertAt(xApps.messageList.message[2].xmlChildren,2,xmlElemNew(xApps,'forPage'))>

but was getting an error.

changed the code to below and all works fine.  thanks for your time

<cfset arrayInsertAt(xApps.messageList.message.xmlChildren,2,xmlElemNew(xApps,'forPage'))>
