Stripping out characters

[idesdema]

I have an <img string that I want to manipulate. Here is the string.

<img src=" http://site.com/1.jpg" width="177" height="240" alt="image" />

The first thing I want to do is strip out the <img src=" and that is common on all the paths I want to manipulate so I thought I could do a simple Replace(). Then I'd end up with http://site.com/1.jpg" width="177" height="240" alt="image" />

I need to strip everything else off that string after the "

I'm not sure how to do that... can anyone help me out?




By the way, BKBK and Ian... that logout code is logging me out on all machines except my laptop at home. I'm about 80% satisfied with it. I still want to know why it won't work from my laptop.

Try This:

<cfset var = '<img src=" http://site.com/1.jpg" width="177" height="240" alt="image" />'>

<cfoutput>#ReReplace(ReReplace(var,'<img src=',''),' width="177" height="240" alt="image" />','')#</cfoutput>

I will be repeating this function over many database entries. The entries are similar but not the same. For example, the width and height and alt values are usually different.

Anyone?

I would be reluctant to use this code
but at least it should get you going...

<cfsavecontent variable="link">
<img src=" http://site.com/1.jpg" width="177" height="240" alt="image" />
</cfsavecontent>

<cfset img = ListFirst(ListRest(link, '"'), '"') />

<cfoutput>
#img#
</cfoutput>

So you want to extract the src value from an <img/> tag? That was a very
long-winded way of describing what you need ;-)

Use a regex, and you can do it in one expression.

Match this: <img.*?src="([^"]*?)"[^>]*?>
Replace it with: \1

Pls take the time to read the regex docs and understand the solution I've
given you...

I read and understand. However, is there a source you recommend for regex tutes?

Here's another silly way to do it...

<cfsavecontent variable="link">
<img src=" http://site.com/1.jpg" width="177" height="240" alt="image" />
</cfsavecontent>

<cfset doc = XmlParse(link) />

<cfset img = doc.img.XmlAttributes.src />

<cfoutput>
[#img#]
</cfoutput>
