XML grep
 

hi everyone, I am having trouble parsing the xml file to get the info between the tag ,
<filename>2010-08-14_hr-nagendra_horizons-in-modern.mp4</filename>

thanx for your help!

We can't help you if you don't explain your issue completely? what language are you doing this in etc.?

ok, I have an xml file which is as below

<archive version="1.0">
<filename>2010-08-14_hr-nagendra_horizons-in-modern.mp4</filename>
<title>Horizons in modern medicines and yoga theraphy </title>
<presenter>Dr. H. R. Nagendra</presenter><description/><unit>NCast Telepresenter</unit>
<channel>FACULTY_send</channel>
<start>2010-08-14 04:33:45</start>
<duration>01:21:08</duration>
<timezone>-0700</timezone>
<width>1024</width>
<height>768</height>
<aspect_width>1024</aspect_width>
<aspect_height>768</aspect_height>
<main_window>0,0,1024,768</main_window><pip_window>716,537,256,192</pip_window><bitrate>1088</bitrate><framerate>25</framerate>
<file_format>mp4</file_format>
<video_format>h264</video_format>
<audio_format>aac</audio_format></archive>


now I want to get the text between the tags <filename></filename> using grep

I tried using: grep '^<filename>*' file.xml, but it gives me output as:
<filename>2010-08-14_hr-nagendra_horizons-in-modern.mp4</filename>
I don't want that tags to be displayed when using grep
soory for not providing this info earlier!

Grep is the wrong choice here. I would suggest awk or sed. As an example:

thanks!
 

That definitely solved this problem! thanks a lot!

Oddly I was looking at xml2 yesterday. that would take any xml and convert it into a much more parseable set of bash strings you can manipulate. just pipe the text into it and it spits it out the other end.

yeah .. i looked into it. I seems to make the tasks a lot easier but it seems complicated. dunno if a newbie like me will be able to harness it fully. thanks anyway!

really? it just makes basic XML really easy to grep and cut. Doddle I thought.

xml2
 

allright! I will follow ur advice and play with it for a while..

well if you've only got that ONE thign to do then you've done it already!

I know but xml2 looks interesting... no harm in playing for a while!!!
