extract DCR node value without tag

Hello,
When you use <iw_value name = 'x.y'/> tag to extract a value from a DCR node, it outputs the value inside tag. For instance the expression mentioned in the earlier sentence will produce something like some value
Is there any way where I can extract just the value without the tag?
I tried using iwpt_dcr_value(), didn't help...
Any idea?
Thanks,
Cliffhanger

I haven't experienced that -- what type of field is x.y? It sounds like a VFE field and there's several things you can do to prevent this, if this is the case.

Please provide more detail.

Hi Dave,
You're right! X is the container name, and Y is a VFE item. How could I prevent the tag in this case?
Thanks

You could have a FormAPI remove the heading and trailing of your field when the DCR is saved (onSaveValid) or you could do the same thing in Perl when your presentation template opens up. Also, depending on what version you're using, you could customize your VFE by classifying and as dirty HTML, i.e. marking it for "cleaning" when instructing the VFE to "clean the HTML."

Either of the first two is better than the third. Besides, the third is a more manual process and would strip out all paragraph tags.

Thanks Dave! I was aware of the first two options, was looking forward for some solution that's more straight forward, which doesn't seem like a possibility now

Hi Dave,
In my DCT I am using a customized VFE that doesn't provide bolding or italizing facilities, however users who know keyboard shortcuts will still be capable of bolding text, underlining, etc.
From my experience I've seen VFE putting tag for such actions, so one way to avoid that would be stripping out the tags.
Do you have any better way in mind that would achieve the same goal?
Thanks

Well, you could call the HTMLClean function (the usage escapes me right now but I know there's information on DevNet about it) as you're saving the DCR, including the tag and its variants in the list of HTML to be scoured.

hmmm...that's where the problem begins, I don't want to clean up all the span tags, only the ones introduced by the usage of keyboard shortcuts....

Aaah, I see. I haven't ever tried this so I can't guarantee this would work, but what if you were to declare an onKeyPress event that would check for this?

Of course, the bottom line is that they'll put the span tag in there whether you want them to or not. For instance, they COULD just type it in the HTML. You shouldn't have to go through hoops for this though -- I think at this point, the solution gets into "user education".

Thoughts?

thanks for your suggestion! as you know, "user education" is usually the last option Smiley Happy

I never rely on 'user education'. In a TPL I use a cleanup code that strips off whatever I need to.

But then, how does he (presumably a "he") accomplish stripping off only *some* of the tags, for instance? No algorithm can be defined here, but he might be able to associate it with onKeyPress (or something similar) in VFE.

Again, I've never attempted events this granular, so it's just my idea at this point... not proven.

dave,
although onKeyPress sounds reasonable, there'll be a tremendous overhead, because their every key press will trigger that event. Where one out of every1000 key press might be the one of our concern.....
However, I found some work around, specific to my scenario. It turns out that the "Style" is defined so that there shouldn't be any tag for the particular section of text that I was concerned about, so I can strip off the tags without any second thought Smiley Happy

Thanks to all of you
