If the html is in a string, e.g. 's':
$(s).html() would return everything inside the outer div.
If it includes more than just that error, you can do something like:
$(s).find('div.error').html()

Hi,
Thanks for the reply. However, your code only seems to be any good
with the actual page content you are on, not the values of a string?
Remember, this data is coming through as a string (as a response from
a jQuery .post() function, so the returned HTML then holds errors
which may have occured - and I need to pick up on those :))
TIA

Hi,
Thanks. Ok, I have this string (for example):
html
head/head
body
bit of other junk here, and maybe other divs and stuff
div class=error
ul
liGast Email der Rezension
kann nicht den Wert 'undefined'
speichern./li
/ul
/div
some junk here
/body
/html
So how exactly would I extract that from a string?
TIA :)

And you can simply use .text() method. This will return you only the
text
inside your selected element.
Do you also need tips on getting the child elements on that div?

Based on jquery documentation:
First, you can define your selectors, it's the easier way if you already
work with CSSs:
http://docs.jquery.com/Selectors
You can use something like: $('.error ul li').text(); to match all
li's
inside the element with class set to 'error' (the . referees a element
using
class name right after the dot).
You can also use $('.error ul li').text() to get each li descending
from a
ul than from a element with a class named 'error'. In our .text() method
this won't make much diference than using the first selector.
Now let's try some jquery methods without complicating our basic
selector:
We have the .find() and .children() methods
From now I'm adapting the text from jquery documentation to our example:
In most cases two selections made with and without find() are
equivalent,
such as $('.error').find('li') and $('.error ul li'). However, using a
selector filter may lead to unexpected results:
$('.error').find('li:first').length may be 1, (whereas $('.error
li:first').length will never be 1) as there is an implicit each() done
within find().
In other words: you can try to select the first li of all div with the
class
attribute named 'error'.
Now the .children(), this method will return all the immediate
descendants
elements within the selected element.
Example: $('.error').children('ul').children('li') this will return
exactly
the directly children of the .error! .find() would return all
descendants,
not only the immediate ones.
As said in the jquery documentation, it's important to refrain here:
while
.children() returns only the immediate descendants, .parents() will look
at
all ancestors.
That's all,
Have a good day.
