Want to know the meaning of ""/^\s+|\s+$/g" in xsl
Hi,
Can someone tell me what does the below string does? the first parameter to the replace function looks like its a regex but have no idea what it does.. can someone help me decipher it!!
This was found in a xsl file and in a function which performs the trimming of a given string.
I am very much keen to know the meaning of "/^\s+|\s+$/g"
Thanks in advance

function stringTrim(instring)
{
var outstring = instring;
return outstring.replace(/^\s+|\s+$/g,"");
}
