How to capture the contents between the tags?

Hello All,

I need to apply the separate character style for the punctuations between the tags, please refer the sample below:

<cite>1</cite>, <cite>5</cite>-<cite>8</cite>

Here I need to apply the seprate character style for the contents like ',', '-' which are found above between the close and open tags. Please advise how we can catch these contents using JS?

PS: I can catch the tag <cite> using the XPath concepts in JS.

Thanks in advance,

Praveen
