Regexp - global replace of a character between tags

[MB]

I need to replace all occurances of a certain character located between
two tags. I have included an example of what i have come up with so far,
but it doesn't work they way I want it to:

str = "some content<script type=\"text/javascript\">var str =
'asdfasdfASDFASDF';<\/script>";
str = str.replace(/(<script.*?>.*?)a(.*?<\/script>)/gim, "$1X$2");
alert(str);

In this example, i want all 'a' between the script tags to be replaced
by 'X', but only the first is replaced. How can I modify this to replace
*all* occurances of 'a'?

str = str.replace(/(<script.*?>)(.*)(?=<\/script>)/gi, function(x,y,z)
{return y+z.replace(/a/gi,'Z')})

Thanks. This works well, however only as long as the contents of 'str'
is just one line. It does not find any matches when I have several
lines. I tried adding the m-flag to the regular expressions, but that
didn't work. Can this be solved too?

str = str.replace(/\n/g,'\uffff').replace(/(<script.*?>)(.*)(?=
<\/script>)/gi, function(x,y,z) {return y+z.replace(/a/gi,'Z')}).replace(/
\uffff/g,'\n')
