Like https://go.dev/cl/481376 did for encoding/gob, but now for encoding/xml, which had very similar code. One minor difference is that encoding/xml now needs a SetLen before the call to Index, as otherwise we index just past the length. Still, calling Grow and SetLen is easier to understand, and avoids needing to make a new zero value. goos: linux goarch: amd64 pkg: encoding/xml cpu: AMD Ryzen 7 PRO 5850U with Radeon Graphics │ old │ new │ │ sec/op │ sec/op vs base │ Unmarshal-8 6.904µ ± 1% 6.980µ ± 1% +1.10% (p=0.009 n=6) │ old │ new │ │ B/op │ B/op vs base │ Unmarshal-8 7.656Ki ± 0% 7.586Ki ± 0% -0.92% (p=0.002 n=6) │ old │ new │ │ allocs/op │ allocs/op vs base │ Unmarshal-8 188.0 ± 0% 185.0 ± 0% -1.60% (p=0.002 n=6) Change-Id: Id83feb467a9c59c80c7936aa892780aae7e8b809 Reviewed-on: https://go-review.googlesource.com/c/go/+/483135 TryBot-Result: Gopher Robot <gobot@golang.org> Reviewed-by: Michael Knyszek <mknyszek@google.com> Run-TryBot: Daniel Martí <mvdan@mvdan.cc> Reviewed-by: Ian Lance Taylor <iant@google.com>
2023-01-31encoding/xml: allow overriding by empty namespaceConstantin Konstantinidis
The namespace defined by xmlns="value" can be overridden in every included tag by the empty namespace xmlns="" without a prefix. Method to calculate indent of XML handles depth of tag and its associated namespace is still active even when no indent is required. An XMLName field in a struct means that namespace must be enforced even if empty. This occurs only on an inner tag as an override of any non-empty namespace of its outer tag. An attribute is added to have the required namespace display.

2021-03-15encoding/xml: replace comments inside directives with a spaceFilippo Valsorda
A Directive (like <!ENTITY xxx []>) can't have other nodes nested inside it (in our data structure representation), so there is no way to preserve comments. The previous behavior was to just elide them, which however might change the semantic meaning of the surrounding markup. Instead, replace them with a space which hopefully has the same semantic effect of the comment. Directives are not actually a node type in the XML spec, which instead specifies each of them separately (<!ENTITY, <!DOCTYPE, etc.), each with its own grammar. The rules for where and when the comments are allowed are not straightforward, and can't be implemented without implementing custom logic for each of the directives. Simply preserving the comments in the body of the directive would be problematic, as there can be unmatched quotes inside the comment. Whether those quotes are considered meaningful semantically or not, other parsers might disagree and interpret the output differently. This issue was reported by Juho Nurminen of Mattermost as it leads to round-trip mismatches. See #43168. It's not being fixed in a security release because round-trip stability is not a currently supported security property of encoding/xml, and we don't believe these fixes would be sufficient to reliably guarantee it in the future.

2021-03-15encoding/xml: handle leading, trailing, or double colons in namesFilippo Valsorda
Before this change, <:name> would parse as <name>, which could cause issues in applications that rely on the parse-encode cycle to round-trip. Similarly, <x name:=""> would parse as expected but then have the attribute dropped when serializing because its name was empty. Finally, <a:b:c> would parse and get serialized incorrectly. All these values are invalid XML, but to minimize the impact of this change, we parse them whole into Name.Local.

fieldInfo.value used to initialize nil anonymous struct fields if they were encountered. This behavior is wanted when decoding, but not when encoding. When encoding, the value should never be modified, and these nil fields should be skipped entirely.

2018-12-12encoding/xml, encoding/json: docs and examples using custom marshalersLeigh McCulloch
Both the encoding/xml and encoding/json packages support custom marshalers for JSON and XML, as well as the basic encoding.TextMarshaler and encoding.TextUnmarshaler interfaces, but the docs and examples for these are missing. There are docs for how to use encoding.TextMarshaler and encoding.TextUnmarshaler in encoding/json, but not encoding/xml. There are no examples for how to use them with either json or xml. This commit includes docs for encoding/xml and examples for both encoding/json and encoding/xml. There is an example using custom marshalers MarshalJSON and UnmarshalJSON in encoding/json, but not MarshalXML and UnmarshalXML in encoding/json. These docs are more so necessary for encoding/xml because the complexities of XML documents is significantly greater than JSON documents which more often leads to the need for custom marshaling. The encoding/json package includes an example of how to write a custom marshaler, and this commit includes the same example for the xml package. All examples are mirrored off the existing custom marshaler example in encoding/json.
