Hi perl Monks, I am a novice perl proprammer. I have developed perl code for html output (two levels list) from short-coded text file. I think the codings are too large. Is there any short way to accomplish it

My input:

<H1>some text</H1>
<NLI>some text</NLI>
<NLI>some text</NLI>
<1NLI>some text</1NLI>
<1NLI>some text</1NLI>
<2NLI>some text</2NLI>
<2NLI>some text</2NLI>
<NLI>some text</NLI>
<H2>some text</H2>
<ALI>some text</ALI>
<ALI>some text</ALI>
<1NLI>some text</1NLI>
<1NLI>some text</1NLI>
<2NLI>some text</2NLI>
<2NLI>some text</2NLI>
<NLI>some text</NLI>
<H2>some text</H2>
<RLI>some text</RLI>
<rLI>some text</rLI>
<1NLI>some text</1NLI>
<1NLI>some text</1NLI>
<2NLI>some text</2NLI>
<2NLI>some text</2NLI>
<aLI>some text</aLI>
