(PowerBuilder) Benefit of XML Methods Having Names Ending in "2"

The Chilkat XML methods having names ending with "2" update the internal reference rather than return a new XML object instance. See the example below..

Note: There are a few methods, such as LoadXml2, where the "2" simply indicates the method is the same but has an additional argument. (There are some programming environments where overloading methods is not allowed. Therefore, Chilkat will avoid providing methods having the same name but with different arguments.)

// First demonstrate getting "123" in the simplest way:
Write-Debug loo_Xml.ChilkatPath("abc|xyz|*")

// Now demonstrate navigating to the "xyz" node using non-"2" methods.
// The following few lines of code create two object instances, which will need
// to be deleted or garbage collected.
loo_XAbc = loo_Xml.FindChild("abc")
loo_XXyz = loo_XAbc.FindChild("xyz")
Write-Debug loo_XXyz.Content
destroy loo_XXyz
destroy loo_XAbc

// Now demonstrate navigating to the "xyz" node using the "2" methods.
// No object instances are created.
li_Success = loo_Xml.FindChild2("abc")
li_Success = loo_Xml.FindChild2("xyz")
Write-Debug loo_Xml.Content
// Restore xml back to the root of the document.
