But, my input_file.txt will have multiple lines like

<b><a href="/home/document.do?assetkey=x-y-abcde-1&searchclause=photo">
<b><a href="/home/document.do?assetkey=x-y-12345-1&searchclause=photo">
<b><a href="/home/document.do?assetkey=x-y-xvyab-1&searchclause=photo">

<b><a href="/home/document.do?assetkey=x-y-56789-1&searchclause=river">
<b><a href="/home/document.do?assetkey=x-y-12345-1&searchclause=river">

after processing the each line from the input_file.txt, I need the ouput files like

abcde.html
12345.html
xvyab.html
56789.html
12345.html
