Removing null tags from XML file in perl
|
Can't Post
|
|
Hi,
We are trying to create a XML extract(with the help of another tool) and then send it to a portal. How can i remove the null tags and the entire null hierarchy from the xml file? I am giving an example of type of null tabs we are getting:
<root>
<level1>
<level2>
</level2>
</level1>
<level1>
<level2>Value</level2>
</level1>
</root>
The output of the script should be
<root>
<level1>
<level2>Value</level2>
</level1>
</root>
I have tried several approaches but the problems i faced were that i was able to traverse to the leaf node ( for valid tags), but was after that there was no way to know whether the immediate parent had a valid value. The output that i got every time was
<root>
<level1>
<level2>Value</level2>
After this i was expecting the closing tags also to come.
Is there a way out to solve this problem(of removing the null hierarchies)?
Thanks
Aditya
