Can you use antixml to create xml documents?
there are a few examples for using Anti-Xml to extract information from XML documents, but none that I could find of using Anti-Xml to create XML documents. Does Anti-Xml support creating documents, or should I use another library for this (which one?). Does anyone have an example of creating an XML document with Anti-Xml?
Yes, you can build (and serialize) XML documents:
import com.codecommit.antixml._ val doc = Elem(None, "doc", Attributes(), Map(), Group( Elem(None, "foo", Attributes("id" -> "bar"), Map(), Group(Text("baz"))) )) val writer = new java.io.StringWriter val serializer = new XMLSerializer("UTF-8", true) serializer.serializeDocument(doc, writer)
You can also use Anti-XML's zippers to do some interesting editing tricks:
val foos = doc \ "foo" val newFoo = foo.head.copy(children = Group(Text("new text!"))) val newDoc = foos.updated(0, newFoo).unselect
Now newDoc contains the edited document:
scala> newDoc.toString res1: String = <doc><foo id="bar">new text!</foo></doc>
Update in response to ziggystar's comment below: if you want something like Scala's XML literals, you can just use convert on any scala.xml.Elem:
val test: com.codecommit.antixml.Elem = <test></test>.convert
I'd assumed the question was about programmatic creation.
Unless you are using other parts of anti-xml I'd stick with Scala's literals. However if you are looking for a better alternative with a nice builder DSL, in place updates, XPath usage (DSL and String based) etc, then I'd suggest a look at Scales. From the 0.3-RC5 release site (http://scala-scales.googlecode.com/svn/sites/scales/scales-xml_2.9.1/0.3-RC5/index.html):
val ns = Namespace("test:uri") val nsa = Namespace("test:uri:attribs") val nsp = nsa.prefixed("pre") val builder = ns("Elem") /@ (nsa("pre", "attr1") -> "val1", "attr2" -> "val2", nsp("attr3") -> "val3") /( ns("Child"), "Mixed Content", ns("Child2") /( ns("Subchild") ~> "text" ) )
Also for direct serialisation you can leverage streaming, as Scales Xml model unifies the model for streaming and tree based processing.
I'm short before a 0.3-RC6 with many more docs (and very cool xml comparison framework) but I'm waiting on migrating to sonatype first. (eta next week)
