XML.au3 - BETA - Support Topic

mLipok · September 2, 2015

I was asking @eltorro serveral times for any support for XML DOM wrapper (COM) - with no success

So I took matters into my hands .....

I want to present XMLWrapperEx.au3 - BETA Version

Want to join to the project ?

Here is some description:

; #INDEX# =======================================================================================================================
; Title .........: XMLWrapperEx.au3
; AutoIt Version : 3.3.10.2++
; Language ......: English
; Description ...: Functions to use for reading and writing XML using msxml.
; Remarks .......: BETA Version
; Author ........: mLipok
; Version .......: "1.1.1.01" ; _XML_MiscProperty_UDFVersion()

#cs
    This UDF is created on the basis of:
    https://www.autoitscript.com/forum/topic/19848-xml-dom-wrapper-com/
    For this reason, I attach also the last known (to me) previous version ($_XMLUDFVER = "1.0.3.98"  _XMLDomWrapper_1.0.3.98_CN.au3 )
    For the same reason I continue to recognize the achievements of the work of my predecessors (they are still noted in each Function header).
    .
    .
    .
    . !!!!!!!!! This is BETA VERSION (all could be changed) !!!!!!!!!
    .
    .
    .
    WORK IN PROGRES INFORMATION:
    For now 2015-09-01 the descripion (Function Header) can not entirely correctly describe the function.
    TODO: in many places I used "TODO" as a keyword to find what should be done in future
    .
    I want to: PREVENT THIS:
    The unfortunate nature of both the scripts is that the func return results are strings or arrays instead of objects.
    .
    I want to: USE THIS CONCEPT:
    .   All function should use Refernce to the object as first Function parameter
    .   All function should return in most cases objects. There should be separate functions to Change Object collection to array
    .   All function should use COM Error Handler in local scope.
    .   All function should return @error which are defined in #Region XMLWrapperEx.au3 - @ERROR Enums
    .    All function should have the same naming convention
    .    All variables should have the same naming convention
    .    There should not to be any Global Variable - exception is $g__oXMLDOM_Events
    .   It should be possible easy to use XML DOM Events
    .        https://msdn.microsoft.com/en-us/library/ms764697(v=vs.85).aspx
    .   It should be possible easy to Debug
    .    Ultimately, you should be able to do anything with your XML without having to use your own Error Handler.

mLipok,

greate idea to start a re-write of this widely-used UDF! :-)

Following points came up to my mind to improve (or keep the state of) this UDF:

- x86/x64 Support (currently working)
- A much better error handling by providing error return codes all over - and their documentation. Perhaps removing '_XMLError()'!?
- Clear code structure, no code blow up (= removing old/useless comments, implementing current AutoIt coding capabilities, consistent variable names, etc.)
- This UDF - presuming a successful re-write - has the potential to be part of the AutoIt built-in UDFs in the future!? Therefore the quality of the UDF has to meet *any* requirements defined by the AutoIt-Devs.

Maybe I could help.

Where to start?

work In progress - look in my UDF and say exactly what is not done already

- This UDF - presuming a successful re-write - has the potential to be part of the AutoIt build-in UDFs in the future!? Therefore the quality of the UDF has to meet *any* requirements defined by the AutoIt-Devs.

I hope that. We must ask dev team.

But we have many TODO

finish entire UDF rewrite (according to UDF-spec and Best coding practices)
make EXAMPLES
get feedback from community
debuging
ask "Dev Team" is it OK ?
make TXT files for HelpFile
ask "Dev Team" is it OK ?
post it to "Dev Team"
wait for AutoIt release

I hope that nothing is missed in my TODO List .

Maybe I could help.

I hope you want, this is first step.
Do it - this is second step

Where to start?

Right here where you read this topic. (Well, unless your question was of a different nature.)

Best regards,

mLipok

typo, wording, UDF TODO List rewrite.

supersonic · September 3, 2015

This could be a bit larger project - so "Where to start?" means that any work should be organized/coordinated in some way...

To have any chance this UDF to become an AutoIt built-in UDF the AutoIt devs should be asked before start coding...!?

guinness · September 3, 2015

AutoIt devs should be asked before start coding...!?

Not really, because even if we say no, that shouldn't stop anyone from re-writing and posting in the examples section. Having it included as an official UDF is basically peace of mind for some people, though honestly whether it's in AutoIt or examples section, these days doesn't really matter.

But please continue to re-write. If the code is structured well enough and all "checkboxes" for submission are checked, then I might be convinced to spend some time adding to the UDFs. Though again I make no guarantees that it will be included and will have to be impressed. As the current UDF isn't ready for submission!

mLipok · September 3, 2015

As the current UDF isn't ready for submission!

I know.

mLipok · September 3, 2015

Can you enumerate what at the moment is inconsistent with the standard for the UDF (Maybe not necessarily now, because I know that is a lot of room for improvement.)

I know that I can read about it here.

But unfortunately still my language skills are sometimes a problem for me.
Therefore, the above specification often seems to me that is not clear.
Much less clear if analyzed the current standard UDF, which I understand they were created prior to this specification.

btw.
I guess I finally open a new thread with questions about the current specification for the UDF (as I had planned).
A separate thread will be a good solution that does not "messes up" the thread in which I'm writing now.

EDIT:

for reference only:

Hey community, this is "AutoIt Projects and Collaboration" so I need some feedback.
Do not be shy, get involved.

So I ask you, even if you're among us shortly.

What you mean about:

_Example_3__XML_Misc_ErrorDecription
the way I use Error Handler in local scope

??

any comments are welcome

Little off topic story

Maybe you're wondering why I got involved in running such a large project.
The answer is simple: I just wanted to learn XML technology.
Over a year ago I read the various threads on this forum, I started using XMLDomWrapper.au3, but quickly found that has a lot of problems and errors. I was disheartened so my learning XML was pushed into the background.
After some time, I was bored, so I looked at the cabinet with unread books. The choice fell on "XML seriously." - (Polish book of 2002). Even though it's old, I started reading, and a little knowledge became for me to understand.
A month ago I returned to XMLDomWrapper.au3, and I started to analyze any problem with XML, which was discussed at that time in the forum.
At the same time non-stop, still I peek at MSDN.
At a time when "AutoIt Projects and Collaboration" was created, I knew that ultimately here this story will have its future course. But to move from the place it was necessary to give the course. So I started continue to analyze XMLDomWrapper.au3, and at the same time I started to change it.
So we are here and now.

Maybe I could help.
Where to start?

This could be a bit larger project - so "Where to start?" means that any work should be organized/coordinated in some way...

I hope you get involved, even through testing and comments, it would be good if you gave it some concepts, or just added some of your code.

member @DarkAqua asked for help here:

and was redirected by @KingBob here.

The question was intresting for me so I make this exmaple:

    ; Add user ComError handler ; it will be used toogether with internal ComError handler
    _XML_ComErrorHandler_UserFunction(_ErrFunc_CustomUserHandler)

    Local $sXmlFile = @ScriptDir & "\_test\tasks.xml"
    Local $oXmlDoc = _XML_CreateObject()
    _XML_Load($oXmlDoc , $sXmlFile)
    ; MsgBox($MB_SYSTEMMODAL + $MB_ICONINFORMATION, 'tasks.xml', _XML_TIDY($oXmlDoc))


    Local $oNodesColl = _XML_SelectNodes($oXmlDoc, "//Task")

Script changed to met current UDF stage

guinness · September 7, 2015

Global used inside a function? Come @mLipok, you should know better than that. Change to Local and you should be good.

Edit: Also I noticed this comment "; TODO Magic Number Remove", but message boxes shouldn't be in UDFs like this. Also documentation doesn't quite match some of the function signatures.

Edited September 7, 2015 by guinness

mLipok · September 7, 2015

From the current work:

. Removed: almost all MsgBox() - leaves only in __XML_Misc_MsgBoxNotifier()
. Changed: in Examples : Global $oErrorHandler >> Local $oErrorHandler

mLipok · September 7, 2015

Also documentation doesn't quite match some of the function signatures.

I know.

You can read in UDF header

WORK IN PROGRES INFORMATION:
For now 2015-09-01 the descripion (Function Header) can not entirely correctly describe the function.

As you see this is known issue, and to fix this it should take some time, as I going step by step.
For this I made a Keyword system for checking:

@DONE - this keyword is usefull for bookmark finished functions

And I add many TODO keyword for remember.

Regardless of this, big thanks for reminder.

I temporary add to the UDF new region: #Region XMLWrapperEx.au3 - TOOLs
