How to replace value only if it occurs at the start of the field

Following on from my earlier question I’ve been experimenting with the post-function functionality. I’m extracting a block of text but want to remove blank lines. Phil provided a snippet of JavaScript to replace multiple “<br /&gt;” with a single one.

What I’m trying to do now is remove ANY that occur at the start of the string. The text extracted is “<br />The Owner<br />of a prop<br /><br />”.

The caret is the normal method of anchoring the comparison to the beginning of the string but I can’t get it to work. My post-function reads replace(/^<br /&gt;/,“”); If I remove the caret it removes the 1st occurrence so I’m thinking I must have an error in my caret.

Any pointers?

Thanks

Try:

replace(/^&lt;br \/&gt;/,"")

You only need to “escape” (i.e. with the \ ) the “/” character inside the BR token.

Hi Doug,

You can try this RegExp, which should work with your text extracted.

.replace(//gi, " ");

This code will replace all on your extraction and replace it for a white space.

You can check an example with your extraction clicking on this link https://jsfiddle.net/jcwdeveloper/54y1s6ke/

Please let me know if it’s works for you.

Best Regards,

Thanks Juan,

Odd isn’t it. For days now I’d been struggling with this. Come in this morning, type in a regexp and it worked! I’d ended up with replace(/(\s+)|(){2}/g,“”).replace(/^/,“”);

The first replace gets rid of white spare and double and the second replace removes any from the start. Might not be pretty but it works!

Thanks

Doug
