Help manipulating a plist file

Hi there,
Here is a section of the file:
Code: Select all
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>2d955670-b357-4848-8a27-b0c8eaeaf367</key>
<dict>
<key>AccountURL</key>
<string>pop://sales%40doobox.co.uk@mail.doobox.co.uk/</string>
<key>Signatures</key>
<array>
<string>950E3D7D-234D-4DA7-9345-957635200E39</string>
<string>1dooboxsig</string>
</array>
</dict>
<key>AllSignaturesKey</key>
<array>
<dict>
<key>SignatureIsRich</key>
<false/>
<key>SignatureName</key>
<string>Signature #1</string>
<key>SignatureUniqueId</key>
So i have the file contents, and i currently have them displayed in a field, visible on the stack.
The file content is stored in a variable called:
filecontent
I think i could explain that better in plain English.. Soory this is mixed with livecode, but i guess you guys that know, will know what is and what is not:
Code: Select all
open file specialFolderPath("Home") & "/Library/Mail/Signatures/SignaturesByAccount.plist" for read
read from file specialFolderPath("Home") & "/Library/Mail/Signatures/SignaturesByAccount.plist" until EOF
local filecontent
put it into filecontent
search filecontent for all instances of an email address between the string values of
"<key>AccountURL</key>" and "<key>Signatures</key>"
put search result into theemailaddresses
put theemailaddresses into field emailaccounts // i am ok with this
upon clicking any of the addresses do this: // i am ok with this line
local mynewarray ="<array>
<string>950E3D7D-234D-4DA7-9345-957635200E39</string>
<string>newsigniture</string>
</array>"
put mynewarray into the file at the specific point
just before closing </dict> on the <dict> that the clicked email address resides in.
Any help with any stage of the above would be appreciated.

I just cant get the basics of this.
I am trying some tests, here is an example:
Code: Select all
on mouseUp
local thetext
put field "Shakespeare" into thetext
// thetext now contains the complete plist file
replaceText(field "Shakespeare","<key>AccountURL</key>","replacementtext")
// error: button "Write": execution error at line 5 (Handler: can't find handler) near "replaceText", char 1
end mouseUp
Why is that generating an error..?

Hi,
A function returns a value, which needs to be put into something. You always need to get or put a function: put replaceText(...).
Kind regards,
Mark

Hi there,
I did manage to put together something that will modify the plist file to my needs:
Code: Select all
on mouseUp
local thetext, myreg
put field "editor" into thetext
put "(?<=\<key>Account)((?:.|\s)*?)(?=\</array>)" into myreg
put replaceText(field "editor",myreg," The replacement text ") into field "preview"
end mouseUp
However i have been warned off this approach, using regex on html..!
What are my alternatives in live code..?
Kind regards
Gary

Hi Gary,
I think your regex will find only one instance of an e-mail address or URL (it isn't entirely clear to me what you're looking for). It might be more effective to use a repeat loop to find all key tags and check if they contain an e-mail address or URL. For example, you could use offset("<key",myData,myOldOffset). The third parameter in the offset function is very useful, although it can be somewhat complicated to get it to work correctly.
Kind regards,
Mark

I am at different times looking for or to replace different things. I should focus on the one in hand.
There are potentially multiple instances of:
Code: Select all
<key>AccountURL</key>
<string>pop://sales%40doobox.co.uk@mail.doobox.co.uk/</string>
<key>Signatures</key>
<array>
<string>950E3D7D-234D-4DA7-9345-957635200E39</string>
<string>1dooboxsig</string>
</array>
That regex in the above post was my testing / trying to locate all instances of this block.
I guess i would put each instance into an array. Then loop over that array running a regex on each block to extract the email addresses.
I will use these addresses in the app.
At a later time i want to write another array back to that file in the correct location.
So the code at the top there ^.. will become:
Code: Select all
<key>AccountURL</key>
<string>pop://sales%40doobox.co.uk@mail.doobox.co.uk/</string>
<key>Signatures</key>
<array>
<string>950E3D7D-234D-4DA7-9345-957635200E39</string>
<string>1dooboxsig</string>
</array>
<array>
<string>MyNewIdHere</string>
<string>1newIdentifierHere</string>
</array>
I can easily get the info from the app and construct the new array ready to inject into the file.
It is the all the regex that is my failing.

Who knows what the hokey cokey looks like..?
Because i am doing it right now
Success, i have the email addresses parsed.
Code: Select all
on mouseUp
repeat for each line theLine in field "editor"
if theLine contains "%40" then
put theLine & return after tList
end if
end repeat
put replaceText(tList,"<string>(.*?)//",empty) into tList
put replaceText(tList,"@(.*)",empty) into tList
put replaceText(tList,"%40","@") into tList
put tList into field "result"
end mouseUp
