PBDOM_PROCESSINGINSTRUCTION

Hi guys!

I have PB 2019 R2 and for the first time I have to create XML document with PBDOM.

So at the beginning of new xml file I have to write Processing instruction:

<? xml version="1.0" encoding="utf-8" standalone="yes"?> 


My sample code:

PBDOM_PROCESSINGINSTRUCTION pbdom_proc
PBDOM_DOCUMENT pbdom_dokument
PBDOM_ELEMENT pbdom_elem_root,pbdom_acc_header
PBDOM_ELEMENT pbdom_orgid
PBDOM_ATTRIBUTE pbdom_attr
PBDOM_TEXT pbdom_txt

pbdom_dokument = Create PBDOM_DOCUMENT

pbdom_dokument.NewDocument("Accounting")

pbdom_elem_root = pbdom_dokument.GetRootElement()

pbdom_acc_header = Create PBDOM_ELEMENT
pbdom_orgid= Create PBDOM_ELEMENT

pbdom_acc_header.setname("AccontingHeader")

pbdom_orgid.setname("OrganizationId_DK")
pbdom_orgid.AddContent("2")

pbdom_elem_root.AddContent(pbdom_acc_header)

pbdom_acc_header.AddContent(pbdom_orgid)

pbdom_dokument.savedocument("c:\test.xml")

/////////////////////

How and where to code Processing instructions that will be at the beginning of xml file? Could someone show me?

Thanks and stay healthy!

Thank you Daryl,

that was solution I was looking for!

I got impression that not many PB developer use PBDOM for xml processing? Do you all use Datawindows xml templates?

I am missing some good example of using PBDOM in PB documentation, and also in PB Example App.

Hi Tomaz, I haven't really used xml for about 10 years, the last time was in Powerbuilder 10.5. Most of my current work is using JSON. When I did use xml, I mainly used the Datawindow xml templates for creating xml. It was pretty good once I worked out what I was doing. From memory you can use nested reports to create nested xml from a data window.

I also used PBDOM occasionally for modifying (or combining) the xml generated from the Datawindow template xml.

My main use of PBDOM was for parsing existing xml for processing rather than for creating xml. It is quite powerful once you get the hang of it.

There are no comments made yet.

Hi Govinda,

Sample which you sent to me doesn't describe problem I have. In general I understand XML.

I have problems creating new XML with PBDOM, especially with PBBOM_PROCESSINGINSTRUCTION class.

I don't know how to incorporate in xml documents.

If I find a code sample using this class I'll share it to you through here.
