(Visual FoxPro) Demonstrate the XML "I" Property

Demonstrates the XML "I" property. The properties I, J, and K can be used in paths to access the I'th, J'th, or K'th child in a path. Three indexing properties are provided to allow for triple-nested loops using this feature.

Note: This example requires Chilkat v9.5.0.64 or later.

* This example uses the XML document at https://www.chilkatsoft.com/exampleData/xero_accounts.xml
* The data is a download of the Xero accounts for the sandbox company test data (it's not real data).

* We'll use Chilkat HTTP to download the XML.
* This example assumes the Chilkat HTTP API to have been previously unlocked.
* See Global Unlock Sample for sample code.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbXml = CreateObject('Chilkat.StringBuilder')

* Download the XML from https://www.chilkatsoft.com/exampleData/xero_accounts.xml
* into sbXml
lcUrl = "https://www.chilkatsoft.com/exampleData/xero_accounts.xml"
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')
lnSuccess = loHttp.QuickGetSb(lcUrl,loSbXml)
IF (lnSuccess <> 1) THEN
    ? loHttp.LastErrorText
    RELEASE loSbXml
    RELEASE loHttp
    CANCEL
ENDIF

lnBAutoTrim = 0
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Xml')
loXml = CreateObject('Chilkat.Xml')
loXml.LoadSb(loSbXml,lnBAutoTrim)

* How many accounts exist?
lnNumAccounts = loXml.NumChildrenAt("Accounts")
? "numAccounts = " + STR(lnNumAccounts)

i = 0
DO WHILE i < lnNumAccounts
    loXml.I = i
    ? "AccountID: " + loXml.GetChildContent("Accounts|Account[i]|AccountID")
    ? "Name: " + loXml.GetChildContent("Accounts|Account[i]|Name")
    ? "Code: " + STR(loXml.GetChildIntValue("Accounts|Account[i]|Code"))
    ? "EnablePaymentsToAccount: " + STR(loXml.GetChildBoolValue("Accounts|Account[i]|EnablePaymentsToAccount"))
    ? "----"
    i = i + 1
ENDDO

* The output looks like this:

* 	numAccounts = 69
* 	AccountID: ceef66a5-a545-413b-9312-78a53caadbc4
* 	Name: Checking Account
