XML.au3 - BETA - Support Topic

mLipok · September 9, 2015

I was working on:

Func _XML_GetAttrib(ByRef $oXmlDoc, $sXPath, $sAttribute_Name)
    Local $oXML_COM_ErrorHandler = ObjEvent("AutoIt.Error", "__XML_ComErrorHandler_MainFunction")
    #forceref $oXML_COM_ErrorHandler

    _XML_UseEventHandler($oXmlDoc)
    __XML_IsValidObject($oXmlDoc)
    If @error Then Return SetError(@error, @extended, $XMLWRAPPER_RESULT_FAILURE)

    Local $oNode_Selected = $oXmlDoc.selectSingleNode($sXPath)
    If @error Then
        Return SetError($XMLWRAPPER_ERROR_XPATH, 0, $XMLWRAPPER_RESULT_FAILURE)
    EndIf

    If $oNode_Selected = Null Then
        Return SetError($XMLWRAPPER_ERROR_NONODESMATCH, 0, $XMLWRAPPER_RESULT_FAILURE)
    EndIf

    Local $oAttribute = $oNode_Selected.getAttributeNode($sAttribute_Name)
    If IsObj($oAttribute) Then
        Return SetError($XMLWRAPPER_ERROR_OK, 0, $oAttribute.value)
    EndIf

    If $oAttribute = Null Then
        Return SetError($XMLWRAPPER_ERROR_NOATTRMATCH, 0, $XMLWRAPPER_RESULT_FAILURE)
    EndIf

    Return SetError($XMLWRAPPER_ERROR_GENERAL, 0, $XMLWRAPPER_RESULT_FAILURE)

EndFunc   ;==>_XML_GetAttrib

and was thinking about such a refactoring:

Func _XML_GetAttrib(ByRef $oXmlDoc, $sXPath, $sAttribute_Name)
    Local $oXML_COM_ErrorHandler = ObjEvent("AutoIt.Error", "__XML_ComErrorHandler_MainFunction")
    #forceref $oXML_COM_ErrorHandler

    _XML_UseEventHandler($oXmlDoc)
    __XML_IsValidObject($oXmlDoc)
    If @error Then Return SetError(@error, @extended, $XMLWRAPPER_RESULT_FAILURE)

    Local $oNode_Selected = $oXmlDoc.selectSingleNode($sXPath)
    If @error Then
        Return SetError($XMLWRAPPER_ERROR_XPATH, 0, $XMLWRAPPER_RESULT_FAILURE)
    ElseIf $oNode_Selected = Null Then
        Return SetError($XMLWRAPPER_ERROR_NONODESMATCH, 0, $XMLWRAPPER_RESULT_FAILURE)
    EndIf

    Local $oAttribute = $oNode_Selected.getAttributeNode($sAttribute_Name)
    If IsObj($oAttribute) Then
        Return SetError($XMLWRAPPER_ERROR_OK, 0, $oAttribute.value)
    ElseIf $oAttribute = Null Then
        Return SetError($XMLWRAPPER_ERROR_NOATTRMATCH, 0, $XMLWRAPPER_RESULT_FAILURE)
    EndIf

    Return SetError($XMLWRAPPER_ERROR_GENERAL, 0, $XMLWRAPPER_RESULT_FAILURE)

EndFunc   ;==>_XML_GetAttrib

as you see I used ElseIf what you think about ?

Since I'm still at the beginning of the road, then I can from now on, use this approach.
Always a few lines less, and besides a piece of code is intertwined / grouped, making it easier to understand.

BrewManNH · September 9, 2015

You might want to use an Else in there as well so that the last Return statement is part of the If/Then/Endif conditonal. I'm not sure but it looks like it only hits the last Return statement if everything else hasn't fired off a Return statement first.

BTW, you don't need to use #forceref in this function, it's not needed.

Func _XML_GetAttrib(ByRef $oXmlDoc, $sXPath, $sAttribute_Name)
    Local $oXML_COM_ErrorHandler = ObjEvent("AutoIt.Error", "__XML_ComErrorHandler_MainFunction")
;~   There shouldn't be any need to use #forceref in this function
;~     #forceref $oXML_COM_ErrorHandler

    _XML_UseEventHandler($oXmlDoc)
    __XML_IsValidObject($oXmlDoc)
    If @error Then Return SetError(@error, @extended, $XMLWRAPPER_RESULT_FAILURE)

    Local $oNode_Selected = $oXmlDoc.selectSingleNode($sXPath)
    If @error Then
        Return SetError($XMLWRAPPER_ERROR_XPATH, 0, $XMLWRAPPER_RESULT_FAILURE)
    ElseIf $oNode_Selected = Null Then
        Return SetError($XMLWRAPPER_ERROR_NONODESMATCH, 0, $XMLWRAPPER_RESULT_FAILURE)
    EndIf

    Local $oAttribute = $oNode_Selected.getAttributeNode($sAttribute_Name)
    If IsObj($oAttribute) Then
        Return SetError($XMLWRAPPER_ERROR_OK, 0, $oAttribute.value)
    ElseIf $oAttribute = Null Then
        Return SetError($XMLWRAPPER_ERROR_NOATTRMATCH, 0, $XMLWRAPPER_RESULT_FAILURE)
    Else
        Return SetError($XMLWRAPPER_ERROR_GENERAL, 0, $XMLWRAPPER_RESULT_FAILURE)
    EndIf
EndFunc   ;==>_XML_GetAttrib

Yes you have right.

It could be done even his way:

Local $oNode_Selected = $oXmlDoc.selectSingleNode($sXPath)
    If @error Then
        Return SetError($XMLWRAPPER_ERROR_XPATH, 0, $XMLWRAPPER_RESULT_FAILURE)
    ElseIf $oNode_Selected = Null Then
        Return SetError($XMLWRAPPER_ERROR_NONODESMATCH, 0, $XMLWRAPPER_RESULT_FAILURE)
    Else

        Local $oAttribute = $oNode_Selected.getAttributeNode($sAttribute_Name)
        If IsObj($oAttribute) Then
            Return SetError($XMLWRAPPER_ERROR_OK, 0, $oAttribute.value)
        ElseIf $oAttribute = Null Then
            Return SetError($XMLWRAPPER_ERROR_NOATTRMATCH, 0, $XMLWRAPPER_RESULT_FAILURE)
        Else
            Return SetError($XMLWRAPPER_ERROR_GENERAL, 0, $XMLWRAPPER_RESULT_FAILURE)
        EndIf
    EndIf

Recently I change my habbits and I do not like to go in depth in code structure.
But in this case this is not DEEP .

BTW, you don't need to use #forceref in this function, it's not needed.

In this snippet yes you have right.
But as a part of UDF it should stay beause I use:

#AutoIt3Wrapper_Au3Check_Parameters=-d -w 1 -w 2 -w 3 -w- 4 -w 5 -w 6 -w 7

at the begining of this UDF.

BrewManNH · September 9, 2015

I see that you need to use #forceref when you use the -w 5 parameter, I don't tend to use it myself as it doesn't make any difference to whether the script runs correctly or not.

mLipok · September 9, 2015

I'm not sure but it looks like it only hits the last Return statement if everything else hasn't fired off a Return statement first.

My logical analysis shows that, this function _XML_GetAttrib() should never invoked $XMLWRAPPER_ERROR_GENERAL.

but as a security system should be used, for any case.

I see that you need to use #forceref when you use the -w 5 parameter, I don't tend to use it myself as it doesn't make any difference to whether the script runs correctly or not.

But is usefull when you want create clean code with out any garbage (unused variables, constants ....)
So I still use this feature.

Errate:

. If user do not set it and something goes wrong with COM then this is USER PROBLEM and NOT UDF ISSUE/ERROR
. in such case UDF will call empty function for avoid AutoIt Error

Actually I'm wondering about such a question:

Is there any difference in results beetwen this two lines:

$oXmlDoc.documentElement.selectNodes($sXPath)
$oXmlDoc.selectNodes($sXPath)

I think its related with how $sXPath is used.

Any quick explanation ?

Recently I make this:

. REFACTORED: all this following function uses _XML_SelectNodes() - mLipok
.       _XMLCreateChildNode()        _XML_DeleteNode()            _XML_GetAllAttribIndex()
.       _XML_GetParentNodeName()    _XMLSetAttrib()            _XML_UpdateField2()
.       _XMLGetValue()                _XML_GetNodesCount()        _XML_ReplaceChild()
.       _XML_GetNodesPath()           _XMLGetAllAttrib()
. REFACTORED: all this following function uses _XML_SelectSingleNode() - mLipok
.       _XML_CreateAttribute()        _XML_CreateComment()        _XML_GetAttrib()
.       _XML_GetChildNodes()        _XML_GetChildren()            _XML_NodeExist()
.       _XML_RemoveAttribute()        _XML_GetChildText()        _XML_UpdateField()
.       _XMLGetField()

I have an idea.
I'm thinking on changing concept that this function should have as parameter $oNodesColl or $oNode instead $sXPath.
In that case _XML_SelectSingleNode() and _XML_SelectNodes(), should be thrown out these functions.

So I want to ask: what you mean about this concept ?

I think __XML_ComErrorHandler_UserFunction
Should not be internal.

User should be able to setup his own Function for COMErrorHandler for each separate UDF just after #include section, and do not worying about this in any other place.

for example

In a future I would like to use this kind of code:

#include "xml.au3"
#include "XZIP.au3"
#include "SQL.au3"
#include "DEBENU.au3"
#include "CHILLKAT.au3"
#include "PDFCREATOR.au3"


; This error hanlder will be used globally excepting inside UDF Functions
; unles you set it up for UDF with _UDFNAME_ComErrorHandler_UserFunction
Global $oErrorHandler = ObjEvent("AutoIt.Error", ErrFunc_CustomUserHandler_MAIN)
#forceref $oErrorHandler


_XML_ComErrorHandler_UserFunction(ErrFunc_CustomUserHandler_XML)
_XZIP_ComErrorHandler_UserFunction(ErrFunc_CustomUserHandler_XZIP)
_SQL_ComErrorHandler_UserFunction(ErrFunc_CustomUserHandler_SQL)
_DEBENU_ComErrorHandler_UserFunction(ErrFunc_CustomUserHandler_DEBENU)
_CHILLKAT_ComErrorHandler_UserFunction(ErrFunc_CustomUserHandler_CHILLKAT)
_PDFCREATOR_ComErrorHandler_UserFunction(ErrFunc_CustomUserHandler_PDFCREATOR)


_Main()
Func _Main()
    ; user script start here
    ; .......
    ; .......
    ; .......
EndFunc

Of course, the user can define one function for all UDF as follows:

#include "xml.au3"
#include "XZIP.au3"
#include "SQL.au3"
#include "DEBENU.au3"
#include "CHILLKAT.au3"
#include "PDFCREATOR.au3"


; This error hanlder will be used globally excepting inside UDF Functions
; unles you set it up for UDF with _UDFNAME_ComErrorHandler_UserFunction
Global $oErrorHandler = ObjEvent("AutoIt.Error", ErrFunc_CustomUserHandler_MAIN)
#forceref $oErrorHandler


_XML_ComErrorHandler_UserFunction(ErrFunc_CustomUserHandler)
_XZIP_ComErrorHandler_UserFunction(ErrFunc_CustomUserHandler)
_SQL_ComErrorHandler_UserFunction(ErrFunc_CustomUserHandler)
_DEBENU_ComErrorHandler_UserFunction(ErrFunc_CustomUserHandler)
_CHILLKAT_ComErrorHandler_UserFunction(ErrFunc_CustomUserHandler)
_PDFCREATOR_ComErrorHandler_UserFunction(ErrFunc_CustomUserHandler)


_Main()
Func _Main()
    ; user script start here
    ; .......
    ; .......
    ; .......
EndFunc

These questions are important from the point of view of further action on the UDF but also for others.
I would just about handling errors by COMErrorHandler finish and move on.

Therefore, the request for an opinion what do you think in general about the way that has been presented here by me.

mLipok

EDIT: By the way, manner discussed here, will be used also in modifications for ie.au3 (I will publish soon Beta version)

I just want to say that I have tremendous respect for mLipok for taking on this tremendous task, and the rate of updates is staggering and encouraging. Also, thanks to all those like guinness and anyone else who works on these UDF's out of ... whatever motivation they may have.

I think this and the recent OO_JSON.au3 do make sense for future inclusion as native libraries... but I don't know how that process works.

I'am using Autoit lastest version 3.3.12 - 14.0 . This Script is not working . It's too much error :

- ERROR OPEN FILE WITH BOM

- $OBJ_NAME is not declare

- With statement is invalid

mLipok · October 20, 2015

Which SciTE version you are using ?

scila1996 · October 20, 2015

Which SciTE version you are using ?

Version 3.4.4
Jul 13 2014 20:07:38

I'am very want your script may be best working ! Please help me to do use !

mLipok · October 20, 2015

https://www.autoitscript.com/cgi-bin/getfile.pl?../autoit3/scite/download/SciTE4AutoIt3.exe

Try to update

EDIT:

- $OBJ_NAME is not declare

$OBJ_NAME is defined in

#include <AutoItConstants.au3>

Which is included by at top of XMLWrapperEx.au3 UDF.

- With statement is invalid

Show me SciTE console output.

Thank you ! I was runned this script, may be it's have so much Features more than XMLWRAPERE . If can you do the few Example for each function ?

Thank you !

mLipok · October 21, 2015

If can you do the few Example for each function ?

I have such a plan. But now I'm working on other AutoIt project.

For now you should check XMLWrapperEx__Examples.au3
You can find there few examples.

btw.
Remember
!!!!!!!!! This is BETA VERSION (all could be changed) !!!!!!!!!

Generaly function in:

#Region XMLWrapperEx.au3 - Functions - Work in progress
; .......
#EndRegion

#Region XMLWrapperEx.au3 - Functions - Not yet reviewed
; .......
#EndRegion

are Work In Progress so you must have it in mind that this function can change entirely.

scila1996 · October 21, 2015

_XMLCreateFile ?

How do i use ?

#include "XMLWrapperEx.au3"

Local $oXMLDoc = _XMLCreateFile(@ScriptDir & "\settings.xml", "SETTINGS", True)

This code is not working !

mLipok · October 21, 2015

Did you check @error and @extended ?
