Re: [xml-dev] XML Parsing in Go

Should also add that I have only used the built-in parser once and it did a serviceable job. I used it to help a team understand the contents of some large XML files which had no DTD or XSD. Pretty printed they came to about 10K lines. I essentially computed counts of the elements, certain values of some attributes, etc.

While at one point, I had to ask a question on one of the Go forums (or was it Stack Overflow??), I encountered little trouble and it did everything I needed.

Cheers,

Cecil

The "tagged" structs in Go are more flexible than first appearances may show, but the built-in xml parser doesn't give a lot of options.

Over at godocs.org a search on xml show some that may be of interest. But I can't vouch for any of them:
- a pull parser https://godoc.org/github.com/mmcdole/goxpp
- a streaming parser https://godoc.org/mellium.im/xmlstream (work in progress)
- one that claims to follow the W3 standard https://godoc.org/github.com/tdewolff/parse/xml
- a "event based" parser https://godoc.org/github.com/lucsky/go-exml
- one that builds a tree of Go values https://godoc.org/aqwari.net/xml/xmltree

HTH,

I'm looking into a project that will do some XML parsing and likely be
implemented in Go. What do folks think of the available libraries? All
I see so far seems to be based on the rather broken notion of data
binding. (One more time: XML documents are not structs.)

Is there any rough equivalent to SAX, DOM, or XOM for Go that supports
XML in its full generality? For now I can live without external entity
resolution. Validation would be nice but is not absolutely essential.
I do need to support mixed content and elements that don't necessarily
appear when and where you expect them, though.
