Lightbulb Use xmlstarlet inside an if loop

I have a XML file of little huge size. I have to build a logic to get the count of the tag


And have an if loop such that all the <capacity> blocks are captured one after the other.

sample input file - sample1.xml


Please find the below snippet for achieving my goal

set -x
sensor_count=`grep -c "<capacity>" sample1.xml`
for ((i=1;i<=$sensor_count;i++));
        xmlstarlet sel -t -c '//capacity["$i"]' -n sample1.xml

Now the problem is when I use the $i variable along the xmlstarlet command it is printing the entire file rather than
only the occurence.
# 2  
I don't know about the xmlstarlet syntax, but at any rate, the use of single quotes is preventing the variable i from being expanded.

So try changing :
