Help with Comparison of RTF files

Recommended Posts

Hi Guys

I have two RTF files. I want it to compare the two files every line and every word and report the differences logically if found any.

My main constraint is, we do not have any line numbers like we have in a notepad and textpad. If that is present in RTF, then i could say for example:

Line 023 in File1 is "ABC"

Line 023 in File2 is "DEF".

I have no clue how can i proceed as there is no standard template. Any idea is welcome.

Sample.RTF

Sample1.rtf

Does this help?

Read those files into variables and after that you can compare them as you want.

#include <Word.au3>
ConsoleWrite( _checkWord("c:downloadssample.rtf") & @CRLF)
Func _checkWord($path)
Local $oWordApp = _WordCreate($path, 0, 0, 0)
Local $oDoc = _WordDocGetCollection($oWordApp, 0)
; Store document text to a variable
$sText = $oDoc.Range.Text
_WordQuit($oWordApp) ; Close MS Word
Return $sText
EndFunc   ;==>_checkWord

Scripts & functions Organize Includes Let Scite organize the include files

I'm afraid it'll be more difficult. The number of ways to create/edit any RTF file while obtaining the exact same result is unbounded.

Given the samples that the OP posted, I don't see any efficient way to perform a comparison based on resulting content, irrespective of variations in internal arrangement of statements.

Word for instance has a document comparison feature but I guess you don't want to use that. What could possibly work is a resulting formatted text comparison but even then, you'll have to use some RTF rendering program.

WinMerge has a lot of plugins which could help here. For Winword there is the CompareMSWordFiles.dll available.

I'd be tempted to read them line by line into 2 arrays, that way you have line numbers sorted. Now, if the RTFs are for something pretty structured almost like an ini then the checks could be done in Autoit reasonably easily though I could see it being faily long-winded. Otherwise you could output each line to a temporary TXT file and use the CMD line file compare (FC), I fear that might be very slow though.

What jchd tries to tell is that even when two RTF files - when displayed - look the same their internal structure in the file may be different.

Symbolic:

"<bold><red>This is a test</red></bold>" isn't the same as ""<red><bold>This is a test</bold></red>"

What needs to be done is to take boths files, extract the pure text and then compare.

Hence I would try Xenobiologist's solution.

Still reasonably simple to use Xeno's method and feed them into arrays to be a little more granular control, Unless of course the only difference is an extra line feed at the start in which case then treating the whole file as a single variable is obviously the only way to go. It is all very much dependant on the expected data in the file, hence my comment about ini type structure. A line count of both files might allow for some of that, but as you say, a difference in 'gramatical' layout is more tricky to allow for.

If that sort of control was required, then striping the blank lines then separating the whole file into sentances then taking each and finding matches in the second file (and number of matches) would be the way to go. Embeded pictures would need a different aproach, Maybe extracting them and a checksum and filesize compare? I assume that is a touch extreme though.
