Remove \n using regular expression in javascript

I have a javascript string contains html table like this:

  <div class="nobrtable"><table class="at"><TBODY><TR><td> FY

  </TD><td> Profit Margin

  </TD><td> Asset Turnover

   </TD><td> RoA

   </TD><td> Leverage Ratio

   </TD><td> RoE

   </TD><td> Cash Conversion

   </TD><td> Cash RoE

   </TD><td> RoC

    </TD></TR><TR><td> 2002

     </TD><td> 5.1%

    </TD><td> 1.42

     </TD><td> 7.2%

      </TD><td> 127%

      </TD><td> 9.2%

      </TD><td> 163%

      </TD><td> 14.9%

      </TD><td> 16.9%

      </TD></TR>

      </TD></TR></TBODY></table></div> 

How开发者_如何学运维 could I using regular expression to remove all the '\n' in the table? Otherwise it is too long.

I tried using

ele = ele.replace(/\n/g, ' ');

It will replace all the '\n' in my string. I just want to remove all the '\n' in all the html tables.

Thanks!

Try this:

ele = ele.replace(/\s+<\/TD>/g,' </TD>')

/m on the regex means match multi-line which helps matching on multiple \n's in a string.

UPDATE

• dropped the /m modifier
• changed \s* to \s+
• introduced a whitespace character in the replacement string as browsers will render a whitespace character after your text in the TD, which you may want (though better to use no space and use CSS for padding/margins

Try this:

ele = ele.replace(/\n<\/TD>/g, '</TD>');

I'm not sure if you're talking about the HTML source or the inner HTML at runtime, butyou could try trimming the inner HTML of each TD element as follows:

var tds=document.getElementsByTagName('td'), i;
for (i=0; i<tds.length; i++) {
  tds[i].innerHTML = tds[i].innerHTML.trim();
}

Assuming you have original text in a variable called html following should work for you:

var m = html.match(/<table[\s\S]*<\/table>/i);
var tableWithoutNewLine = m[0].replace(/\n/g, '');
html = html.replace(/<table[\s\S]*<\/table>/i, tableWithoutNewLine);

After this code variable html will have all the new line \n replaced between <table and </table tags only while leaving all other new lines and spaces intact.
