The aim of this data type is to provide the possibility of recording XML files or strings.
In order to be able to create an XML file or string from a GeneXus object you must define an XMLWriter data type variable and then invoke the methods needed to create the nodes that compose it.
The following procedure generates a file called MEETING.xml that contains the data for a meeting, indicating the people who participated in it and their corresponding tasks.
For Each
&XMLWriter.Open('MEETING.xml')
&XMLWriter.WriteStartDocument()
&XMLWriter.WriteStartElement('MEETING')
&XMLWriter.WriteAttribute('Date', DToC(ReuFch))
&XMLWriter.WriteElement('DATE', DToC(ReuFch))
&XMLWriter.WriteComment('Meeting Description')
&XMLWriter.WriteCData(ReuDsc)
&XMLWriter.WriteStartElement('MEMBERS')
For Each
&XMLWriter.WriteElement('MEMBER',ReuPerNom)
Endfor
&XMLWriter.WriteEndElement()
&XMLWriter.WriteStartElement('TASKS')
For Each
&XMLWriter.WriteStartElement('TASK')
&XMLWriter.WriteElement('PERSON_IN_CHARGE',ReuTarPerNom)
&XMLWriter.WriteCData(ReuTarDsc)
&XMLWriter.WriteEndElement()
EndFor
&XMLWriter.WriteEndElement()
&XMLWriter.WriteEndElement()
&XMLWriter.Close()
Endfor
The MEETING.xml file contains:
<?xml version="1.0" encoding="ISO-8859-1" ?>
