stringhashtml =: ...
You might try this definition instead:
stringhashtml =: (rxcomp '(?i)<html>[^\0]*</html>')
&(0&<:@:((<0 0)&{)@rxmatch)
Examples:
stringhashtml 'no html'
0
stringhashtml '<html>yes html</html>'
1
stringhashtml '<HTML>caps html</HTML>'
1
stringhashtml '<HtMl>mixed case html</hTmL>'
1
stringhashtml '<html>',({.a.),'uh oh, a null</html>'
0
stringhashtml '<html>unclosed html'
0
I hope this one doesn't crash on you. Good luck.
