Auto-Trim XML Content when Loading

See more XML Examples

This example explains the "autoTrim" argument that is passed to a method such as LoadXml2. PowerBuilder

integer li_rc
long li_Success
oleobject loo_Xml
long li_AutoTrim

li_Success = 0

loo_Xml = create oleobject
li_rc = loo_Xml.ConnectToNewObject("Chilkat.Xml")
if li_rc < 0 then
    destroy loo_Xml
    MessageBox("Error","Connecting to COM object failed")
    return
end if

//  If autoTrim is 1, then the content inside an leaf element is trimmed.
//  For example:
li_AutoTrim = 1
loo_Xml.LoadXml2("<abc><xyz>  123   </xyz></abc>",li_AutoTrim)
Write-Debug loo_Xml.GetXml()

//  Output is:
//  (notice the SPACE chars before and after "xyz" are trimmed)

//  <?xml version="1.0" encoding="utf-8" ?>
//  <abc>
//      <xyz>123</xyz>
//  </abc>

//  If autoTrim is 0, then the content inside leaf elements are not trimmed.
li_AutoTrim = 0
loo_Xml.LoadXml2("<abc><xyz>  123   </xyz></abc>",li_AutoTrim)
Write-Debug loo_Xml.GetXml()

//  Output is:

//  <?xml version="1.0" encoding="utf-8" ?>
//  <abc>
//      <xyz>  123   </xyz>
//  </abc>

//  --------------------------------------------------------------------
//  The EmitCompact property controls whether XML is emitted indented (pretty-printed)
//  or compact.  For example:

//  Auto-trim + emit compact:
li_AutoTrim = 1
loo_Xml.LoadXml2("<abc><xyz>  123   </xyz></abc>",li_AutoTrim)
loo_Xml.EmitCompact = 1
Write-Debug loo_Xml.GetXml()

//  Output is:

//  <?xml version="1.0" encoding="utf-8" ?>
//  <abc><xyz>123</xyz></abc>

//  No Auto-trim + emit compact:
li_AutoTrim = 0
loo_Xml.LoadXml2("<abc><xyz>  123   </xyz></abc>",li_AutoTrim)
loo_Xml.EmitCompact = 1
Write-Debug loo_Xml.GetXml()

//  Output is:

//  <?xml version="1.0" encoding="utf-8" ?>
//  <abc><xyz>  123   </xyz></abc>
