[oXygen-user] Format & Indent multiple files?

Hello Roger,

We do have a request logged on our issue tracking tool for a batch 
"Format and Indent" action (in the Project view). I added your vote and 
gave it a nudge.

If you have a reasonable number of files that you want to apply this to, 
you could use a workaround:
1. Enable in Options > Preferences, Editor > Format, the option "Format 
and indent the document on open"
2. Set the format and indent options you want in Editor > Format and 
Editor > Format > XML preference panels
3. Close all files.
4. From the Project view open a batch of files you want to format (20-30 
at a time, more if they are very small). Right click on selection and 
from contextual menu pick 'Open All Files'.
5. Look at a few files if the formatting looks right to you.
6. File > 'Save All' files.
7. Repeat from step 3 until all files are formatted.
8. Disable the option "Format and indent the document on open" from step 1.
9. If Oxygen slows down significantly or runs out of memory while 
opening the files, it means you gave it a batch larger than it could 
handle. If that happens, close all the files without saving and restart 
Oxygen. Try again with a smaller batch.

I guess you could also use a batch transformation in Oxygen (on a folder 
or a set of files) and use the Saxon formatting options. You can use a 
copy stylesheet similar to the one found in the Oxygen samples, 
Although I must point out that DOCTYPEs will be lost and entity 
references will be expanded (replaced with the referred entity value) 
when you apply a transformation.

Oxygen applies the transformation scenario in turn for each file from 
the selected files and folders from the Project view. Note that you have 
to configure the transformation scenario to transform one XML file and 
output it to another file (you can't output to the same file as the 
input file), so the output file must either have a different name or be 
located in a different folder. Either way, an output file name (not 
folder name) must be provided in the Output tab of the transformation 
scenario. You can use editor variables (macros) to refer the filename an 
folder path of the source file.

If you use the Saxon-HE/PE/EE transformer engine, I would also recommend 
disabling the option "Expand attribute defaults" (default enabled) from 
the "Advanced options" (cogwheel button to the right of the transformer 
combo). By default this is enabled and causes default values of 
attributes specified in the DTD/schema to appear in the XML model and as 
a result also the copied output.
