Wildcard F/R

I've checked through the other posts, and I think I understand how to do a variable find and replace, but I'm missing the obvious it seems...

I have a few html files that have code like this in it...
<IMG src="thumbnails/th_My%20Photo.jpg"

I need to replace it with:
<IMG src="../vwimages/th_My%20Photo.jpg/$FILE/th_My%20Photo.jpg"

So should I be doing a simple find and replace or a batch?

I think this is how it should be done...
<IMG src="thumbnails/th_(.*).jpg"

<IMG src="../vwimages/$1/$FILE/$1.jpg"

Does this make sense at all?

In this version of Advanced Find and Replace you can use regular
expressions on Batch Replace tab.

The right regular expressions pair is:

Search for:
<IMG src="thumbnails/(th_.*)\.jpg"

Replace with:
<IMG src="../vwimages/$1/$FILE/$1.jpg"

. - dot before jpg is reserved char in search for (but not in replace
with!). So you have to escape it with \

Then in your example you have to put ( before th_

I verified it worked as expected.

I see... so I should be putting this in the expression builder dialog box.. and not manually... correct?

BTW: It did work...

Mucho thanks..

For testing you should put it into Regular Expressions Builder.
Otherwise (for real replace) you should put it into Batch Replace

Still doing some work on this... and for some reason the batch replace grid does not seem to like the '$FILE' piece... is the $ a reserved character?

I notice that it seems to duplicate a large part of the text of the document. e.g. I have a 5x5 table... after the replace, I have a 5 x 10 table.

Exactly. $ is a reserved char.

So in Search For part you should put \ before $ like this:

But in Replace With part you can use $ without \

For example you can use $FILE in Replace With part but you should use
\$FILE in Search For part.

Now what happens in the scenario where there is no "$FILE" in the search part, but is being added in the replace?

e.g. if I am searching for:

and replacing with:

The original string does not contain "$FILE" but is being inserted...

Even after some further testing, I guessing that "$FILE" is another reserved word... I think this copies the whole file and pastes it back in.. which might explain why my tables are being super-sized!
