hey all
I'm using hpricot 0.8.1. I'm setting the contents of some tags using
the inner_html method, and if any of the values i set happen to be empty
strings, it blows up:
xml.search("/data/score/composer").inner_html = "foo"
=> "foo"
xml.search("/data/score/composer").inner_html = ""
/var/lib/gems/1.8/gems/hpricot-0.8.1/lib/hpricot/traverse.rb:198:in
`reparent': undefined method `parent=' for nil:NilClass (NoMethodError)
from
/var/lib/gems/1.8/gems/hpricot-0.8.1/lib/hpricot/traverse.rb:198:in
`each'
from
/var/lib/gems/1.8/gems/hpricot-0.8.1/lib/hpricot/traverse.rb:198:in
`reparent'
from
/var/lib/gems/1.8/gems/hpricot-0.8.1/lib/hpricot/traverse.rb:177:in
`html'
from
/var/lib/gems/1.8/gems/hpricot-0.8.1/lib/hpricot/traverse.rb:192:in
`inner_html='
from
/var/lib/gems/1.8/gems/hpricot-0.8.1/lib/hpricot/elements.rb:96:in
`inner_html='
from
/var/lib/gems/1.8/gems/hpricot-0.8.1/lib/hpricot/elements.rb:96:in
`each'
from
/var/lib/gems/1.8/gems/hpricot-0.8.1/lib/hpricot/elements.rb:96:in
`inner_html='
Anyone know
a) why this is happening and/or
b) a way to set the contents of these tags that won't error on empty
strings?
thanks, max
