Regex in 2 passes or a macro or two?

[Peter_LT]

Hello Folks,

I have about 2,500 occurrences of code which fall into two distinct types.

Example A

Code: Select all

<a href="image/mythicala.jpg" title="View image in new window"
onclick="newpop(this.href,'rel','415','570','0'); return false;">28 July Cabin Luncheon
<img src="image/mythicalz.jpg" width="85" height="120" alt="28 July 1950 Cabin Luncheon Menu cover"
/></a>

Example B

Code: Select all

<a href="img/tktenv1950a.jpg" title="View image in new window"
onclick="newpop(this.href,'rel','570','350','0'); return false;">
<img src="img/tktenv1950az.jpg" width="195" height="116" alt="28 July train ticket envelope"
/><br />
Train Ticket Envelope</a>

The distinct difference between the two is that a <br/ > occurs only in Example B.

I'm attempting to place a small graphic to show that the links open a new window, using two CSS classes. In Example A the first line will become...

Code: Select all

<a class="pu" href="image/mythicala.jpg" title="View image in new window"

Example B will have a span added to the bottom line viz...

Code: Select all

<span class="ext">Train Ticket Envelope</span></a>

Could this be done with regex in 2 passes, bearing in mind that the start text of...
"a href" with "in new window" will be changed to
"a class="ext" href" with "in new window"
for no occurrence of <br /> before closing </a> in a first pass.

I have read and re-read regex help, both in UE and in Topstyle and I'm still very confused, despite several hours of trial and error...
...and as for macros - I'd not know where to begin.

Is my aim too ambitious? This is more or less the last step in my conversion from HTML 3.2 to accessible XHTML1.0 with CSS. I'm dreading the idea of having to change each entry manually one by one.

I've done one page to show <an example of the desired outcome>.

Any advice you could give would be very gratefully received - thanks.

Regular expression in UltraEdit style for example A:

Find: ^(<a href="*"^) ^(title="View image in new window"[~>]+>[~<]+<img src=[~>]+></a>^)
Replace: ^1 class="pu" ^2

Regular expression in UltraEdit style for example B:

Find: ^(<a href="*" title="View image in new window"[~>]+>[~<]+<img src=[~>]+><br />[ ^t^r^n]+^)^(*^)</a>
Replace: ^1<span class="ext">^2</span></a>

Hello Mofi,

Job done!

What can I say, but thank you so much for this. I don't have much hair and this problem was causing me to lose what little I had.

You clearly have this arcane language of Regex at your fingertips. I've got years of dBase IV programming and HTML writing under my belt, but this for some reason Regex still defeats me.

If I can offer a suggestion - it would be good to have a Tutorial Section here, and you'd be a key man in writing the Regex one.

Thanks again!

There are tons of regex tutorials available out there, but only one Mofi right here. Let's save him for the UE specific hair-pullers.

Oh, in that case - absolutely!
