Xml library with control over how empty tags are printed
Hello
I’m looking for a (reliable, stable) library for printing data in an xml-format. What I additionally need is the ability to specify that empty tags should not be abbreviated (don’t ask, banks are apparently not able to read and understand specifications). For example, an empty tag some_tag should be printed like so:
<some_tag></some_tag>
and never like so (which is allowed according to the specification and also the preferred way):
<some_tag/>
I looked at xmerl and did not find this feature. Which other libraries do exist that allow this ?

I added this functionality to
xml_builder_ex.See
empty: :fulloption in a call togenerate/2.Also Liked
JeyHey
It works almost like expected. The only problem is that empty tags have indentation whitespaces as content. I think deleting lines 171 and 192 in file
lib/xml_builder.exwould fix it.Also, the readme defines the dependency as
{:xml_builder, "~> 3.1"}but it only works if it is defined as{:xml_builder_ex, "~> 3.1"}.mudasobwa
It’s not a problem, it is how it worked by design. There is an ability to provide a
format:option togenerate/2and all the formatters would use it. Just gluing empty tags would violate this, so you always had an option to doformat: [*: :indent, tag1: :none, tag2: :none].But since it’s a common expectation to have empty tags glued, I added
empty: :squeezedalongsideempty: :fullwhich does not respect theformatsetting and glues empty tags in (example from tests.)Last Post!

Use
empty: :squeezedif you need it to be<b></b>. I am to leaveempty: :fullfor the cases when users want{:b, nil, nil}AST to be transformed into<b> </b>.
