XML beautifier tool

This post describes a tool that I wrote long time ago. By now I have published a new refactored version of the XML beautifier which solves a few problems of the original tool.

I’m currently working with a system that is communicating with various third parties using web services. There are times when I need to view some of the XMLs or output them for some particular reason. Because of the last reason I wanted the beautifier to be written in PHP so that I could implement it easily. After spending some time googling with keywords like “php xml indent”, “php xml output”, “php xml human readable”, “php xml beautifier” I found that there are some code snippets or incomplete /not fully working classes / functions.

I’ve also tried pear.php.net and there indeed is a package named “XML Beautifier” that is no longer maintained. And I was frightened away by lot’s of dependencies: PEAR, XML Parser, XML Utilities, XML Beautifier .. Brrrr ..

Finally I visited phpclasses.org and found a class named “Beauty XML”. It’s simple, works but has a few bugs. So I modified the class to do the following things:

  • To ignore adding a new level after if finds a tag like <tag />
  • To remove all XML headers
  • To remove white spaces from situations like “</tag2> </tag1>”

You can download the beauty XML or try it out yourself.

I think there still may be some XMLs that don’t get indented nicely and if i don’t find out that myself maybe You will. So please tell me if you do. I’ve also added a simple interface file to view XMLs in your web browser.

Maybe you already have or know a tool that does this job perfectly and I would be happy if you shared this with me.

I recommend this change.
//$newstr = preg_replace(“/>([\s]+)([\s]+)

currently the above would become:

Nice script, thank you!

But it has some problems with which causes indentation but works like a self closing tag….

Nice script, however…

I’ve got no idea why people don’t code with “show errors” turned on. Running this on my trusty WAMP server on PHP 4 and 5, I got several errors (undefined variables and undefined offsets in arrays).

Well, needless to argue, I’ve fixed all bugs (that I could see), and now it works smoother.
You can get my version here:

The changes I’ve made are to fix those problems, nothing else. Mentioning me anywhere is welcomed, but not required. Of course, you can copy the relevant parts (all of the code) into yours.

Kind regards,
Christian Sciberras.

I just started writing a simple PHP XML beautifier then I decided to check google first. Works out of the box and is very streamlined. Thanks!

Nice tool! :)

Nice Post… looking for it and found exactly. Thanks for the Post.. Well your words “I think there still may be some XMLs that don’t get indented nicely and if i don’t find out that myself maybe You will. So please tell me if you do. I’ve also added a simple interface file to view XMLs in your web browser.”… I have an XML file. This script intended nicely over 80% of my file. But the rest 20% is like expanding tree structure. Any clue about it?

Thanks,
Aditya

Simple, Easy, exactly what i needed. Thank you for sharing this!

I think this is the best XML beautifier on Internet i’ve came across. It also works for SOAP.

Would you like to share source code?

It’s available for download Rajesh :) Use it any way you want.
