Print content between two html tags
Hi Expert,

Is there any other way to print and write to a same filename the content between two html tags?

Here the sample:

cat file.html

Code:
<div id="outline">
hello world<br>
</div>
<div id="container_faq">
test1<br>
</div>

<div class="widget_quick">
thead test<br>
</div>

<div id="linkcat-5">
hello<br>
</div>

<div id="left">
first row<br>
second row<br>
third row<br>
<div>
fourth row<br>
fifth row<br></div>
<br>


       <br>
sixth row<br>
seventh row<br>
eight row<br></div>

<br>




<div id="appendix">
hallo<br>
</div>
<div class="widget">
check this<br>
</div>


Code:
sed -n '/<div id="left"/,/<\/div/p' file.html

the output is not what I want
Code:
<div id="left">
first row<br>
second row<br>
third row<br>
<div>
fourth row<br>
fifth row<br></div>

instead the output would be:

Code:
<div id="left">
first row<br>
second row<br>
third row<br>
<div>
fourth row<br>
fifth row<br>
</div>
       <br>
sixth row<br>
seventh row<br>
eight row<br></div>

is there anything to add to the script?

Thanks

Not sure that you could do that with sed. Try this using awk:
Code:
awk '
/<div id=\"left\"/      {P++}

P                       {if (/<div>/)   P++
                         if (/<\/div>/) P--
                         print
                        }
' file
<div id="left">
first row<br>
second row<br>
third row<br>
<div>
fourth row<br>
fifth row<br></div>
<br>


       <br>
sixth row<br>
seventh row<br>
eight row<br></div>

It's not quite what you have as desired output, but as close as you can get without any further playing dirty tricks.

Thanks for this:

I tried the in one line like this:

Code:
awk '/<div id=\"left\"/ {P++} P {if (/<div>/) P++ if (/<\/div>/) P-- print}' file

but is not working and i got this error:

Code:
awk: /<div id=\"left\"/ {P++} P {if (/<div>/) P++ if (/<\/div>/) P-- print}
awk:                                              ^ syntax error
awk: /<div id=\"left\"/ {P++} P {if (/<div>/) P++ if (/<\/div>/) P-- print}
awk:                                                                 ^ syntax error


Thanks

Put semi-colons (;) where the carrot (^) characters are pointing:

Code:
awk '/<div id=\"left\"/ {P++} P {if (/<div>/) P++; if (/<\/div>/) P--; print}' file
