Question

I am trying to replace some content using regular expression. I am able to do that using the following method:

EX: """ The search technique is usefull, the search technique is usefull """
old = 'the'
toreplace = "<span class='highlight' STYLE='background-color:yellow'>" +  old + "</span>"
pattern = re.compile(re.escape(old), re.I)
highlighted_txt = re.sub(pattern,toreplace,A,count)

" <span class='highlight' STYLE='background-color:yellow'>the</span> search tech
nique is usefull, <span class='highlight' STYLE='background-color:yellow'>the</s
pan> search technique is usefull "

But what I want to do is replace the old word with what is found exactly in the content. Like the second "The" should be replaced with

<span class='highlight' STYLE='background-color:yellow'>The</span>

" <span class='highlight' STYLE='background-color:yellow'>the</span> search tech
nique is usefull, <span class='highlight' STYLE='background-color:yellow'>The</s
pan> search technique is usefull "

Answer 1

This fixed my problem

toreplace = "<span class='highlight' STYLE='background-color:yellow'>\g<0></span>"
