Count words/lines between two tags using awk

Shell Programming and Scripting

Is there an efficient

awk

that can count the number of lines that occur in between two tags.
For instance, consider the following text:

<s>
Hi PP -
my VBD -
name DT -
is NN -
. SENT .
</s>
<s>
Her PP -
name VBD -
is DT -
the NN -
same WRT -
. SENT -
</s>

I am interested to know that in between the first set of tags

<s>

and

</s>

there are 5 words (indicated by 5 lines) and in the second set of tags

<s>

and

</s>

there are 6 words (indicated by 6 lines).

The desired output would be as follows:

5
6

How can I write an

awk

that uses my

XML

tags as markers to count this information and obtain my desired output?

Any attempts from your side?

Be it as it may... this one is not too daunting. Try

awk '/<s>/ {ST=NR} /<\/s>/{print NR-ST-1}' file
