Hi,

I am struggling to get this regular expression to work properly and would appreciate if someone could give some help. This what I have tried but to no avail:

/>[\s]\w*\s*/ , ""

I need to clear all the spaces (but only the blank spaces and not content) that are between > </ including the carriage return line feed, if any, between all the tags from the string:

<A t="1"> ad </A> <B t="2"> ba </B>
<C t="3"> rr </C>

It should become this:
<A t="1">ad</A><B t="2">ba</B><C t="3">rr</C>

Also, can someone kindly explain to me what these reg Exp are doing?

s=s.replace(/(<)(input|img|br|hr)([^>]*)/ig,"$1$2 $3 /")

s=s.replace(/=([^"]{1}[^ ">]*)/ig,"=\"$1\"")

s=s.replace(/ (selected|checked|multiple)/ig,function(s,m){x=m.toLowerCase();return " "+x+"=\""+x+"\""})

s=s.replace(/<(\/?[A-Z]+)/ig,function(s){return ""+s.toLowerCase()})

Thanks a lot

Pall

Hii pallone!!

Hope this will help you

<script>

function CallMe()
{
 instr=document.getElementById("input").value



regExp1=/>\s*/g
outstr=instr.replace(regExp1,">")

regExp2=/\s*</g
outstr=outstr.replace(regExp2,"<")

document.getElementById("output").value=outstr
}
</script>
 <input type=button onclick="CallMe()" value="TestRegExp">


<br>
Input String
<textarea id="input" rows=4 cols=60></textarea>
<br>
output String
<textarea id="output" rows=4 cols=60></textarea>


Cheers :)

Hi vinod,

Your example is working. That is brillant. Thanks for you help.

Would it be possible to achieve the same result using only one regular expression?

I have seen some examples online where developers use a $1 to replace. Here are some of the examples I found online but I do not understand it. The first example uses 3 $1$2 $3 to replace.

Could you please elaborate a bit on these?

s=s.replace(/(<)(input|img|br|hr)([^>]*)/ig,"$1$2 $3 /")


s=s.replace(/=([^"]{1}[^ ">]*)/ig,"=\"$1\"")


Cheers
