Do you know why my RE does not match my text

sepgs2004 · Mar 10, 2008

This is the input:
<html:text styleId="dateDue" property="newFee.dateDueString" maxlength="10"
onkeyup="autoFormatDate(this, event)" size="10" onkeypress="digitsOnly()"
onfocus="clearTextField(this)" onchange="dude()" />

My Reg expression is:
onkeyup\s*=\s*"autoFormatDate\s*\(this\s*,\s*event\)"[.\s]*onchange\s*=\s*"(.*)"[.\s]*\/>

I am trying to replace the following
<html ....
onkeyup="autoFormatDate(this, event)"
.....
onchange="dude()"
... />

with

<html ....
onkeydown="autoFormatDate(this, event)"
.....
onchange="newDude(); dude()"
... />

In brief, onkeyup replaced with onkeydown and onchange got one more function/script added. There might be anything including line breaks between this onkeyup and onchange properties in a tag. Another thing is I want to replace/update onchange only if the tag also contains onkeyup="autoformat...".

other points
We can assume onchange is going to follow onkeyup in a tag. This line breaks are the complicated ones that I could not get it matched. I am not sure how to make it restricted to one tag at a time instead of the situation "begining matches one tag and ending matches next tag".

With the above, this does not match my Reg expression.

Thanks

The bit of the regex

Code:

event\)"[.\s]*onchange

is failing because . inside [] is a real dot, not a match anything .

Is that what you mean?

There are quite a few variants of regular expression languages; what language/utility are you doing this in and under what OS?

Try this perl version:

Code:

perl -e '
        # do not read file line-by-line
        local $/=undef;
        while (<>) {
s/onkeyup\s*=\s*"autoFormatDate\s*\(this\s*,\s*event\)"(.*)onchange\s*=\s*"(.*)"/onkeydown="autoFormatDate(this, event)$1onchange="newDude();$2"
/s;
                print;
        }
'

Good point, Annihilannic - I thought I was on the Perl forum

Regardless, you were right. ;-)
