Question

I’m using Dreamweaver to replace a line of code that looks like this

123, //hotspot topValue

with a line of code that looks like this

[123, 123, 123], //hotspot topValue

I suck at regular expressions.. And what makes it even more difficult is that the number I need to keep unchanged is not always three digits but can be sometimes 0 too.

In that case it should go from

0, //hotspot topValue

to

[0, 0, 0], //hotspot topValue

So basically I always take the number on the line that is commented //hotspot topValue and put it inside an array and duplicate it two times.

Is this possible with regular expressions in the find and replace panel? I read that Dreamweaver uses Javascript regular expressions if it helps.

Answer 1

Have a look at dreamweaver’s documentation.

The regular expression you are looking for would be:

Find: ([0-9]+), //hotspot topValue
Replace: [$1,$1,$1], //hotspot topValue

[0-9]+ will match any number of characters 0,1,2,..,9 that occur at least once (+ means one or more). Brackets around it will make it a capture group, meaning that you can then use any content matched inside them as $1. The rest is obvious: match exactly , //hotstop topValue.

Alternatively you can use

Find: ([0-9]+), //(.+)
Replace: [$1,$1,$1], //$2

To match your number followed by any comment (although one must be present).
