Find and Update an XML Attribute Value

See more XML Examples

Demonstrates how to find an element in XML with a specified attribute name and then update the attribute value. AutoIt

; Let's say you have 2 XML files with identical structures as shown directly below,
; and you wish to update the values in the 1st XML file with those in the 2nd XML file.

; <global>
;     <phrase id="2FADisabled" value="2factor authentication disabled"/>
;     <phrase id="2FAEnabled" value="2factor authentication enabled"/>
;     <phrase id="2FAResetFailed" value="Failed to disable two factor authentication"/>
; </global>

; <global>
;     <phrase id="2FAResetFailed" value="Failed to reset two factor authentication"/>
;     <phrase id="2FADisabled" value="2FA authentication disabled"/>
;     <phrase id="2FAEnabled" value="2FA authentication enabled"/>
; </global>

; First, initialize each of the Chilkat XML objects.
; These could be loaded from files, but we'll just create them manually for this example..

$oXml1 = ObjCreate("Chilkat.Xml")
$oXml1.Tag = "global"
$oXml1.UpdateAttrAt("phrase",True,"id","2FADisabled")
$oXml1.UpdateAttrAt("phrase",True,"value","2factor authentication disabled")
$oXml1.UpdateAttrAt("phrase[1]",True,"id","2FAEnabled")
$oXml1.UpdateAttrAt("phrase[1]",True,"value","2factor authentication enabled")
$oXml1.UpdateAttrAt("phrase[2]",True,"id","2FAResetFailed")
$oXml1.UpdateAttrAt("phrase[2]",True,"value","Failed to disable two factor authentication")

$oXml2 = ObjCreate("Chilkat.Xml")
$oXml2.Tag = "global"
$oXml2.UpdateAttrAt("phrase",True,"id","2FAResetFailed")
$oXml2.UpdateAttrAt("phrase",True,"value","Failed to reset two factor authentication")
$oXml2.UpdateAttrAt("phrase[1]",True,"id","2FADisabled")
$oXml2.UpdateAttrAt("phrase[1]",True,"value","2FA authentication disabled")
$oXml2.UpdateAttrAt("phrase[2]",True,"id","2FAEnabled")
$oXml2.UpdateAttrAt("phrase[2]",True,"value","2FA authentication enabled")

; Iterate over attribute values in xml2 and update the same in xml1.

Local $sPhrase_id
Local $sPhrase_value

$oSbPath = ObjCreate("Chilkat.StringBuilder")

Local $i = 0
Local $iCount_i = $oXml2.NumChildrenHavingTag("phrase")
While $i < $iCount_i
    $oXml2.I = $i
    $sPhrase_id = $oXml2.ChilkatPath("phrase[i]|(id)")
    $sPhrase_value = $oXml2.ChilkatPath("phrase[i]|(value)")

    ; Notice how the UpdateAttrAt method's 1st argument is a Chilkat path -- which is an expression
    ; to find the location of the XML element to be updated.
    ; Here we create a path of the form "/A/tagName,attributeName,attributeValuePattern", which means
    ; find the direct descendent of xml2 having tag=tagName, with an attribute=attributeName where the attribute value
    ; matches the attributeValuePattern.  If attributeValuePattern does not contain a "*", then it must match directly.
    ; We'll build a Chilkat path such as "/A/phrase,id,2FADisabled"
    $oSbPath.SetString("/A/phrase,id,")
    $oSbPath.Append($sPhrase_id)

    ; This assumes the corresponding element exists in xml1.
    $oXml1.UpdateAttrAt($oSbPath.GetAsString(),True,"value",$sPhrase_value)

    $i = $i + 1
Wend

; Now see how xml1 has been updated..
ConsoleWrite($oXml1.GetXml() & @CRLF)
