% custom command to expand content before using \ul:
 \newrobustcmd{\xpul}[1]{\GlsXtrExpandedFmt{\ul}{#1}} 


\begin{document}
First approach (inner formatting):
{% scope
 \renewcommand{\glsxtrdefaultentrytextfmt}[1]{\ul{#1}}%
 \ul{Some text about \protect\gls{html}.
 Next use: \protect\gls{html}}
}


Next use: \gls{html}.


Second approach (middle formatting with expanded link text):
\glsresetall
{% scope
 \renewcommand{\glsxtrabbreviationfont}[1]{\xpul{#1}}%
 \renewcommand{\glsxtrregularfont}[1]{\xpul{#1}}%
 \ul{Some text about \protect\gls{html}. Next use: \gls{html}.}
} 

Next use: \gls{html}. 
\end{document}
