Hi guys;

 

I have a problem with a web service response.

 

It retrieve an html format doc, and we need to load the data contained on it into a database. Is there any way or technique in Power Builder 2019 R3 to "translate" the info of the HTML into valid data?

 

In the 2 files attached, I send 2 types of responses we received from the web service. (please see the "Tipo de Contribuyente" tag)

 

Please somebody can help us.

 

Thanks and regards.

Hi Mario;

 What do you mean when you say  ...  "translate" the info of the HTML into valid data?

Regards .. Chris

He means remove all the HTML markup and save the raw data to a relational database.

Hi Armeen ... if that is the case, then something like this should do the job (for example) ... https://www.nirsoft.net/utils/htmlastext.html

FWIW: There are lots of utilities that can do this HTML => TEXT. Just Google around Mario.

Thanks Armeen and Chris.

 

Armeen is right, that's I search; remove all the HTML markup.

But Chris, that's we want to do from PowerBuilder directly?

Chris with the utility you  tell me; it's possible to use it from PowerBuilder?

Hi Mario ... AFAIK - PB does not have the capability natively. You could start an OLE session using the IE Web Browser and after the HTML is loaded, command the WB to perform a "SaveAs Text". You cannot do that with the new built-in WB Control as there is no SaveAs() feature (yet).

Regards ... Chris

This is strange, a web service usually returns XML or JSON. Returning HTML makes it sound like it is running a web page, not a true web service.

Thanks Roland:



Maybe you¨re right: We use this to access. This is a goverment service.

Hi.

Another way to remove html tags in PB 2019 R3 and versions with updated rte control. You can place an rte control to your window. Then you can load your html and save it as txt.

rte_sample.InsertDocument (".\SRI HTML2.html", true, FileTypeHTML!)
rte_sample.savedocument(".\SRI HTML2.txt", FileTypeText!)

That way you have your text. Here is the result of the first one:

Now you can study the output to write your custom import procedure to your datawindow. To do that you should use more than one html files as samples. May not work in older pb versions.
