I am searching for a way to sort XML data on very large files on a UNIX enviroment. Also, I am very new to XML and UNIX as I am an IBM Mainframe person. Any help or examples would be appreciated.

Thanks

Hi

You can store XML files in flat files in unix , extension hardly means in unix becoz unix treates all the devices and folders as files. but then type of file could differ.
To sort file you can use sort command OR for sort on the basis of particular patterns in that file you better can use sed / awk commands.

sed 'script' filename

where script contains..
/pattern/ action
here /pattern/ which you want to search for sorting and
action is ..what ever ou want to perform on the file. (as you want sorting as an action on the pattern.)

For XML manipulation, you can use powerful languages such as Perl/Python that comes with XML parsers that makes parsing XML easy. I am sure you have these tools available on your machine.
eg Perl XML parser . If not, sed/awk and the likes of Unix tools can also be used, albeit a bit tedious.

CoSort for Unix, Version 9, now sorts (and converts to/from) large, flat XML files, among other mainframe (index) and sequential (csv, ldif, etc.) file formats. CoSort also has JCL sort parm conversion tools for MVS and VSE migrations.

Regular expressions are always a solid way to go.

regexp are powerful, but it also depends. if the code is full of regexp, and if something breaks, they make it difficult for administrator/code maintainer to debug and troubleshoot.

CoSort 9.1.3 also runs on Windows for large, flat XML file sorts.

I have a text file, one word per line. I want to arrange the lines alphabetically so I opened it into MS Word and asked Word to sort it. Word said that the list was too big for it. I figure I'll write a program to sort the file. But I wonder if Word can't handle it what things I'll run into and what's the best way to proceed. I have no idea what kind of limits the are on array sizes and such.
