Regular expression to remove -

Question

Hi im new to regular expression. Just want to know how to remove '-' in specific tag in document. I only want to remove the '-' in <TN> tag. Thanks!

<BusinessLine> <TN>905-694-9734</TN> <Type>buslinetype-HG</Type> <Status>InService</Status> </BusinessLine>

Off the top of my head, an HTML parser would probably be a better bet for this. — Tim Biegeleisen, Dec 21 '17 at 07:05

You can use this regex:

(?<=<TN>.*?)\-(?=.*?</TN>)

For Java:

your_string= your_string.replaceAll("(?sim)(?<=<TN>.*?)\\-(?=.*?</TN>)", "");

i usually use the regex for nifi. not in scripting – Edmart Añora Banzil Dec 21 '17 at 07:51
if using php I would use the preg_replace_callback function for JAVA I use a class found here https://stackoverflow.com/questions/375420/java-equivalent-to-phps-preg-replace-callback/375479?noredirect=1#comment2566951_375479 – Bojoer Dec 21 '17 at 07:53
Look-behind group does not have an obvious maximum length near index 10 when using this regex (?<=.*?)\-(?=.*?) – Edmart Añora Banzil Dec 21 '17 at 08:07
it needs Java Regular Expression – Edmart Añora Banzil Dec 21 '17 at 08:08
it works! i use this expression (?!\.*?)-(?=.*?\<\/TN\>) – Edmart Añora Banzil Dec 21 '17 at 08:45
