Question

I have an HTML content and I do this to get the Textual content .

string='<img src="Randomz" alt="Randomz Image">Randomz is the name of the image</img><img src="Randomz" alt="Randomz Image">Randomz is the name of the image</img><img src="Randomz" alt="Randomz Image">Randomz is the name of the image</img><img src="Randomz" alt="Randomz Image">Randomz is the name of the image</img>'
re=(/([<][^<]+>)([^<]+)([<][^<]+>)/g);
newstr=string.replace(re,"$1$2$3");

This give me back the original string.

My problem is that I need to apply another string.replace(regex,$2) before newstr=string.replace(re,"$1$2$3")

That is, I need to apply another regex on the parametrized catch before applying the final solution.

Not sure what you’re doing here, but I guess you’re looking for replace callbacks:

string='<img src="Randomz" alt="Randomz Image">Randomz is the name of the image</img><img src="Random'
re=(/([<][^<]+>)([^<]+)([<][^<]+>)/g);
newstr=string.replace(re, function($0, $1, $2, $3) {
     $2 = do_something_with($2);
     return $1 + $2 + $3;
});

As a side note, regular expressions is not the best tool for html transformations.
