Regex to exclude URL's

I am trying to create a JavaScript program to replace certain patterns of text with links. However due to some of the patterns existing within a URL on the page it blocks the URL links.

I am specifically looking to exclude the pattern if it is contained within a URL so for example here is my current Regex code.

$els.replaceText(/(\bX00[A-Z0-9]{7}\b)/gi, '<span class="context context_ident">$1<\/span>');

Some Example Text:

item :X00132BhJk

www.domain.com/X00132BhJk

www.domainsearch.com/search?ident=X00132BhJk

X00132BhJk

X00132BhJk

The Italic References should be selected and replaced however the references contained within the domain should not. The issue I have been having is when the reference.

Initially I tried \sX00[A-Z0-9]{7}\s but when the reference appears on the far left of the page (First word in the sentence) it doesn't get selected. Equally so it does not select if a full stop follows or a colon precedes.

Is there a way to specifically exclude URL's by excluding / ? and = from being the immediate preceding character but select in all other cases?

Capture (^ start | OR [^/?=] in a negated character class the ones, that must not appear before)

/(^|[^\/?=])(\bX00[A-Z0-9]{7}\b)/gi

And replace with: '$1<span class="context context_ident">$2</span>'

You don't need to escape the frontslash in the closing span tag on the replacement part.

Regex:

^((?:(?![\/?]).)*)(X00[A-Z0-9a-z]{7})(.*)$

Replacement string:

$1<span class="context context_ident">$2</span>$3

You can try with non-capturing parentheses (?:), in your case (?:[^/?=]|^)

replace(/(?:[^/?=]|^)(\bX00[A-Z0-9]{7}\b)/gi, '<span class="context context_ident">$1<\/span>');

(?!^www.*?X00[A-Z0-9]{7}.*$)^(.*?)(X00[A-Z0-9]{7})(.*)$

Try this.

Replace with.

\1<span class="context context_ident">$1<\/span>\2

See demo.

added an m flag as well for multiline match as i have used anchors.
