Please ignore this post - I accidentally double posted (being new and awaiting moderation). My other question about xml is more to the point.

Hi,

Coming from Scala I am looking at Go to port a custom WebDAV daemon I've written.

However... this will require parsing HTTP headers and xml documents (POSTed). HTTP looks ok from what I see, but what I've read from XML with Go's libraries seem to require 1) files and 2) document-to-struct mappings.

I'd really be looking for something that allows me to select a part of a document or tag/attribute as with Scala's \ and \\ functions (which resemble XPath). Any such thing in Go?

You don't need files. xml.NewDecoder accepts any io.Reader.

The xml package's document->struct mapping allows you to select parts of a document via struct tags. For example if you have an element hierarchy:

<body>

<elem1>

<elem2>

foo

</elem2>

</elem1>

</body>

And you wanted to extract the text from elem2 in to a struct you could define it as:

type Thing struct {

Elem2 string `xml:"body>elem1>elem2"`

}

I've found the library quite convenient to use.

Thank you, that's exactly what's needed. I'll experiment.
