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. Visual FoxPro

LOCAL lnSuccess
LOCAL loXml
LOCAL lnAutoTrim

lnSuccess = 0

loXml = CreateObject('Chilkat.Xml')

* If autoTrim is 1, then the content inside an leaf element is trimmed.
* For example:
lnAutoTrim = 1
loXml.LoadXml2("<abc><xyz>  123   </xyz></abc>",lnAutoTrim)
? loXml.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.
lnAutoTrim = 0
loXml.LoadXml2("<abc><xyz>  123   </xyz></abc>",lnAutoTrim)
? loXml.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:
lnAutoTrim = 1
loXml.LoadXml2("<abc><xyz>  123   </xyz></abc>",lnAutoTrim)
loXml.EmitCompact = 1
? loXml.GetXml()

* Output is:

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

* No Auto-trim + emit compact:
lnAutoTrim = 0
loXml.LoadXml2("<abc><xyz>  123   </xyz></abc>",lnAutoTrim)
loXml.EmitCompact = 1
? loXml.GetXml()

* Output is:

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