XMLPARSER.PRG

XML parser for VFP

Version: 1.3

Author: V. Espina

BASIC USAGE

Load the library

Simply addd this code at the begining of your main program:

DO xmlparser

This will create a public object called xmlParser. If you prefer to create local instances instead, you can do it by using the xmlParser class:

SET PROCEDURE TO xmlParser ADDITIVE
..
LOCAL oParser
oParser = CREATEOBJECT("xmlParser")

To parse a XML file

LOCAL oData
oData = xmlParser.Parse("myfile.xml")
IF ISNULL(oData)
  ?xmlParser.lastError
  RETURN
ENDIF
?oData.nodeValue
?oData.node.attribute

To parse a XML string

LOCAL oData
oData = xmlParser.ParseString("<document><hello>World</hello></document>")
IF ISNULL(oData)
  ?xmlParser.lastError
  RETURN
ENDIF
?oData.Hello -> "World"

EXAMPLE #1

** TEST1.XML
<document>
   <customer id="001"  name="VICTOR ESPINA" />
   <invoices>
     <invoice>
       <number>02002</number>
       <date>01/01/2019</date>
       <amount>23.25</amount>
     </invoice>
     <invoice>
       <number>02010</number>
       <date>07/01/2019</date>
       <amount>32.25</amount>
     </invoice>
  </invoices>
</document>

oData = XmlParser.Parse("test1.xml")
?oData.Customer.Id.   --> "001"
?oData.Customer.Name  --> "VICTOR ESPINA"
?oData.Invoices.Count --> 2
oInvoice = oData.Invoices.Items[1]
?oInvoice.number --> "02002"
?oInvoice.amount --> 32.25
