clojure.data.xml — org.clojure/data.xml 0.0.8

Functions to parse XML into lazy sequences and lazy trees and emit these as text.

AsElements clj protocol

as-elements clj

(as-elements expr)

Return a seq of elements represented by an expression.

cdata clj

(cdata content)

check-stream-encoding clj

(check-stream-encoding stream xml-encoding)

element clj

(element tag & [attrs & content])

emit clj

(emit e stream & {:as opts})

Prints the given Element tree as XML text to stream. Options: :encoding <str> Character encoding to use

emit-cdata clj

(emit-cdata cdata-str writer)

emit-event clj

(emit-event event writer)

emit-start-tag clj

(emit-start-tag event writer)

emit-str clj

(emit-str e)

Emits the Element to String and returns it

event clj

(event type name & [attrs str])

event-tree clj

(event-tree events)

Returns a lazy tree of Element objects for the given seq of Event objects. See source-seq and parse.

EventGeneration clj protocol

Protocol for generating new events based on element type

gen-event clj

(gen-event item)

Function to generate an event for e.

next-events clj

(next-events item next-items)

Returns the next set of events that should occur after e. next-events are the events that should be generated after this one is complete.

flatten-elements clj

(flatten-elements elements)

indent clj

(indent e stream & {:as opts})

Emits the XML and indents the result. WARNING: this is slow it will emit the XML and read it in again to indent it. Intended for debugging/testing only.

indent-str clj

(indent-str e)

Emits the XML and indents the result. Writes the results to a String and returns it

indenting-transformer clj

(indenting-transformer)

parse clj

(parse source & props)

Parses the source, which can be an InputStream or Reader, and returns a lazy tree of Element records. Accepts key pairs with XMLInputFactory options, see http://docs.oracle.com/javase/6/docs/api/javax/xml/stream/XMLInputFactory.html and xml-input-factory-props for more information. Defaults coalescing true.

parse-str clj

(parse-str s & props)

Parses the passed in string to Clojure data structures. Accepts key pairs with XMLInputFactory options, see http://docs.oracle.com/javase/6/docs/api/javax/xml/stream/XMLInputFactory.html and xml-input-factory-props for more information. Defaults coalescing true.

qualified-name clj

(qualified-name event-name)

seq-tree clj

(seq-tree parent exit? node coll)

Takes a seq of events that logically represents a tree by each event being one of: enter-sub-tree event, exit-sub-tree event, or node event.

Returns a lazy sequence whose first element is a sequence of sub-trees and whose remaining elements are events that are not siblings or descendants of the initial event.

The given exit? function must return true for any exit-sub-tree event. parent must be a function of two arguments: the first is an event, the second a sequence of nodes or subtrees that are children of the event. parent must return nil or false if the event is not an enter-sub-tree event. Any other return value will become a sub-tree of the output tree and should normally contain in some way the children passed as the second arg. The node function is called with a single event arg on every event that is neither parent nor exit, and its return value will become a node of the output tree.

(seq-tree #(when (= %1 :<) (vector %2)) #{:>} str [1 2 :< 3 :< 4 :> :> 5 :> 6]) ;=> (("1" "2" [("3" [("4")])] "5") 6)

sexp-as-element clj

(sexp-as-element sexp)

Convert a single sexp into an Element

sexp-element clj

(sexp-element tag attrs child)

sexps-as-fragment clj

(sexps-as-fragment)

(sexps-as-fragment sexp)

(sexps-as-fragment sexp & sexps)

Convert a compact prxml/hiccup-style data structure into the more formal tag/attrs/content format. A seq of elements will be returned, which may not be suitable for immediate use as there is no root element. See also sexp-as-element.

The format is [:tag-name attr-map? content*]. Each vector opens a new tag; seqs do not open new tags, and are just used for inserting groups of elements into the parent tag. A bare keyword not in a vector creates an empty element.

To provide XML conversion for your own data types, extend the AsElements protocol to them.

source-seq clj

(source-seq s & {:as props})

Parses the XML InputSource source using a pull-parser. Returns a lazy sequence of Event records. Accepts key pairs with XMLInputFactory options, see http://docs.oracle.com/javase/6/docs/api/javax/xml/stream/XMLInputFactory.html and xml-input-factory-props for more information. Defaults coalescing true.

str-empty? clj

(str-empty? s)

write-attributes clj

(write-attributes attrs writer)

xml-comment clj

(xml-comment content)
