  We have javascript files that are environment specific, and so I was thinking of going down the path of creating a generic way to read in an XML (config) file to store different environment specific settings. I was curious to know if anybody else on here does that (or if not, is there a reason why you don't)?

• Javascript regex: remove space(s) if not surrounded by a letter

  - by user326433

  I'm trying to clean some html text with javascript, there are white spaces included before and after some words (text is poorly formatted). Currently I have this regex: $("#" + target + " *").replaceText(/([\S][\u05B0-\u05C4]*)/gi, '<span class="marked">$1<\/span>'); This will capture all the non white-space characters and wrap them in a span element, but will not capture spaces between words (I need the span). How would you solve this?
