I am trying to remove all words in one list from another list of words.
If I explicitly enumerate the words to remove everything works fine:
gsub(/to /, "",text);
gsub(/in /, "",text);
gsub(/or /, "",text);
but if I try to build the list of words in an array no substitutions are
ever done. How can I properly format the text array to remove the
words?
Thanks!
BEGIN{
j=0;
badwords[j++]= "/<a> /";
badwords[j++]= "/<the> /";
badwords[j++]= "/<in> /";
text = "a fox jumped into and in the river";
text2 = "a fox jumped into and in the river";
gsub(/\<a\> /, "", text);
gsub(/\<the\> /, "", text);
gsub(/\<in\> /, "", text);
print text;
for (i in badwords)
{
gsub(badwords[i], "", text2);
}
print text2;
exit(0);
};
{
}
