[DXML-15] data.xml can't parse own output if there's a colon in an attribute name

Wed, 3 Apr 2013 20:00:02 -0500

Observe:

> (x/emit-str (x/element :NC {"xmlns" "http://example.com" "xmlns:xsi" "http://www.w3.org/2001/XMLSchema-instance" "xsi:schemaLocation" "http://www.example.com/schema.xsd"} (x/element :Foo {} "bar")))
"<?xml version=\"1.0\" encoding=\"UTF-8\"?><NC xsi:schemaLocation=\"http://www.example.com/schema.xsd\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns=\"http://example.com\"><Foo>bar</Foo></NC>"
> (x/parse-str *1)
#clojure.data.xml.Element{:tag :NC, :attrs {:xsi/schemaLocation "http://www.example.com/schema.xsd"}, :content (#clojure.data.xml.Element{:tag :Foo, :attrs {}, :content ("bar")})}
a> (x/emit-str *1)
XMLStreamException Prefix cannot be null com.sun.xml.internal.stream.writers.XMLStreamWriterImpl.writeAttribute (XMLStreamWriterImpl.java:574)
app.services.external.experian.internal.test-data>

(a) the xmlns and xmlns:xsi attributes have disappeared. Not the point of this issue but worth pointing out.
(b) "xsi:schemaLocation" has become :xsi/schemaLocation
(c) emitting a string blows up.

[DXML-14] IllegalArgumentException when trying to emit a boolean value

Thu, 7 Mar 2013 05:39:08 -0600

I can create an element with a boolean value but I can't emit it...

user=> (emit-str (element :something {} false))
IllegalArgumentException No implementation of method: :gen-event of protocol: #'clojure.data.xml/EventGeneration found for class: java.lang.Boolean clojure.core/-cache-protocol-fn (core_deftype.clj:541)

[DXML-13] Support for preserving whitespace between tags

Sun, 10 Feb 2013 04:35:46 -0600

XML parsers can support preserving white space nodes, but clojure.data.xml does not seem to support this functionality.

For example, the following should be able to return true (perhaps with an option to parse-str):

Desired Behavior

(= (clojure.data.xml/element :x {}
                             (clojure.data.xml/element :a {} "foo")
                             " "
                             (clojure.data.xml/element :a {} "bar"))
   (clojure.data.xml/parse-str
     (str "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"
          "<x>"
          "<a>foo</a>"
          " "
          "<a>bar</a>"
          "</x>")))
;=> true

This is the current behavior:

Current Behavior

(= (clojure.data.xml/element :x {}
                             (clojure.data.xml/element :a {} "foo")
                             (clojure.data.xml/element :a {} "bar"))
   (clojure.data.xml/parse-str
     (str "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"
          "<x>"
          "<a>foo</a>"
          " "
          "<a>bar</a>"
          "</x>")))
;=> true

[DXML-10] Support for DOCTYPE when emitting XML

Wed, 14 Nov 2012 02:06:10 -0600

Some consumers of XML files require an explicit DOCTYPE to accept an XML file. data.xml does not currently support the specification of doctypes when emitting XML. When XML is parsed, I believe DOCTYPEs are silently ignored, so there is no representation in the data model for them. The best design is possibly an :doctype option in clojure.data.xml/emit ?

I've attached a web.xml as example.

[DXML-4] Namespaces support

Sun, 21 Apr 2013 19:04:27 -0500

Add support for both parsing and emitting namespace qualified tags and namespaces URI declarations.
It basically follows the underlying Java XML API in giving xmlns:foo attributes "special" treatment.
