Question

Merge Multiple XML Files using a batch file

Asked by: vegasIT

I need to merge multiple (100's) of XML files into one file that I can import into a MySQL database.

There are two parts to this:

1) I need to add a tag for the file name
2) I need the output file to contain all the data plus the new tag for each file that is merged


So for example I have a directory that contains:
2009-09-08-09-21-29_115_112.xml
2009-09-08-09-21-29_115_112.wav
2009-09-08-09-21-03_7028691049_115.xml
2009-09-08-09-21-03_7028691049_115.wav
2009-09-08-09-18-03_100_112.xml
2009-09-08-09-18-03_100_112.wav

etc... I need the xml files combined and then a new tag called <file_name> created for each

So for the 3 xml files above the output would be:

  <recording_info>
  <recording_tag>All Record</recording_tag>
  <recorded_call_id>36329</recorded_call_id>
  <recorder_cid />
  <recorded_cid>Distribution <112></recorded_cid>
  <recorder_account_id />

  <from_account_id>0</from_account_id>
  <from_caller_id>GAGE AND GAGE L <7028691049></from_caller_id>
  <to_account_id>1113</to_account_id>
  <to_caller_id>John Segrest <115></to_caller_id>
  <duration>36</duration>

  <date_created_secs>1252426863</date_created_secs>
  <file_name>2009-09-08-09-21-03_7028691049_115.wav</file_name>
  </recording_info>
  <recording_info>
  <recording_tag>All Record</recording_tag>
  <recorded_call_id>36327</recorded_call_id>
  <recorder_cid />
  <recorded_cid>Kimberly Miles <109></recorded_cid>

  <duration>160</duration>
  <date_created_ts>2009-09-08 09:18:34.037292</date_created_ts>
  <date_created_secs>1252426714</date_created_secs>
  <file_name>2009-09-08-09-18-34_109_95475425.wav</file_name>
  </recording_info>


The original XML file contains everything EXCEPT the <file_name> line. The file name is always the same as the XML file name except that the extension is wav (always)

Then i need the original xml files either deleted or move to a different location like a bak folder or something. All the files are in the same directory and will remain in the same directory.

For your example, can you attach a smaple of the 3 files that you started with?  I'm assuming they contained everything but the <file_name> tag, but not sure if I'm assuming too much.

Does this need to be a DOS batch file, or could something like AWK be leveraged?

by: vegasITPosted on 2009-09-10 at 18:21:16ID: 25306030

You assumption is correct. This is the Whole file for 1:

<recording_info>
  <recording_tag>All Record</recording_tag>
  <recorded_call_id>36327</recorded_call_id>
  <recorder_cid />
  <recorded_cid>Kimberly Miles <109></recorded_cid>
  <recorder_account_id />
  <recorded_account_id>1107</recorded_account_id>
  <from_account_id>1107</from_account_id>
  <from_caller_id>Kimberly Miles <109></from_caller_id>
  <to_account_id>-1</to_account_id>
  <to_caller_id>95475425</to_caller_id>
  <duration>160</duration>
  <date_created_ts>2009-09-08 09:18:34.037292</date_created_ts>
  <date_created_secs>1252426714</date_created_secs>
  </recording_info>

I would prefer batch only because the machine that this will be ran on does not have awk installed... but i can if needed, just looking for a quick easy solution that i can run using the built in scheduler for windows, then once the file is created i can have MySQL take over the DB update part.

Okay, I think this should be pretty close, you might have to adjust as needed.  A couple of notes:

(1) I wrote the output file with a TXT extension, since if I wrote it with an XML extension this file will pick it up since it matches *.XML

(2) Since your data has redirection symbols ("<", ">") in it, I had to quote those strings.  They write to the output file with quotes around them, not sure right off how to remove them.  If this is a one time thing you could open in a text editor and remove them.  If this needs to run unattended then we'll have to research that further.

(3) I didn't add logic to move or delete the original files but that would be straight forward.

I've attached the sample BAT file, and the output TXT file.

~bp

@echo off
setlocal
 
set OutFile=merged.txt
 
for %%a in ("*.xml") do call :DoFile "%%a"
goto :EOF
 
:DoFile
set FileFull=%~f1
set FileName=%~n1
for /f "tokens=*" %%b in ('type %FileFull%') do call :DoLine "%%b"
goto :EOF
 
:DoLine
set Line=%1
if %Line% == "</recording_info>" (
  echo "<file_name>%FileName%.wav</file_name>">>%OutFile%
)
echo %Line%>>%OutFile%
goto :EOF

Well #2 the redirections are going to be a problem,  when i attempt to bring the into the DB they are getting identified as a column in the table so....

If we change the ones that contain a number <109> to "109" or 109; or strip themout totally that would be fine. Would prefer it if they were removed. We can keep each of the lines quoted  that is not causing an issue on the import.

 

by: vegasITPosted on 2009-09-10 at 21:27:07ID: 25306695

also when running the bat file i get a "of was unexpected at this time" and it only writes the first file in the out put.

This may need to be a vb script to accomplish my goal as DOS is apparently not robust enough.

There are some ways to get around those restrictions with the <>. One is this using escaping:

@echo off
setlocal EnableDelayedExpansion
set OutFile=merged.xml
 
(for %%F in (*.xml) do ^
if NOT "%%F" == %OutFile% ^
for /F "tokens=*" %%L in (%%F) do (
  if "%%L" == "</recording_info>" echo ^<file_name^>%%nF.wav^</file_name^>
  echo %%L
)) > %OutFile%

vegasIT,

The embeded "<" and ">" in the data fields would be easy enough to remove, we could add that to this batch file.

As far as the error you are getting, try editing the BAT file and change the @echo off to @echo on.  Then when the error occurs post up the last 10 or 15 lines of screen output, maybe I can see where the problem is.  I tested it here with your three example files and it processed all three.

OK so the code provided by Qlemo works great (almost), by escaping out the char it will import properly into the db and combines the files right. However the output file is creating a problem for me:


....
<date_created_secs>1252427280</date_created_secs>
<file_name>2009-09-08-09-27-59_109_105.wav</file_name>
<file_name>%nF.wav</file_name>
</recording_info>
<recording_info>
<recording_tag>All Record</recording_tag>
<recorded_call_id>36335</recorded_call_id>
<recorder_cid></reco
....

If you look at the <file_name> tags (yes now there are 2) the first one is correct, but the second one is causing an issue... it is not valid and on import it is overwriting the previous one in the db. If i could get rid of that it would be great.

 

by: QlemoPosted on 2009-09-11 at 11:18:31ID: 25312082

Sorry, a single char was "lost in translation" ... See line 8

@echo off
setlocal EnableDelayedExpansion
set OutFile=merged.xml
 
(for %%F in (*.xml) do ^
if NOT "%%F" == %OutFile% ^
for /F "tokens=*" %%L in (%%F) do (
  if "%%L" == "</recording_info>" echo ^<file_name^>%%~nF.wav^</file_name^>
  echo %%L
)) > %OutFile%

Well i think we are getting closer :)

Now it is just putting the filename tag in twice, but it is formatted right, not sure how the second one is getting in there. The file name on that one is not correct.

<date_created_secs>1252427280</date_created_secs>
<file_name>2009-09-08-09-27-59_109_105.wav</file_name>
