# XML
|
|
|
|
Encode and decode to and from XML. Whitespace is not conserved for round trips - but the order of the fields are.
|
|
|
|
Consecutive xml nodes with the same name are assumed to be arrays.
|
|
|
|
XML content data, attributes processing instructions and directives are all created as plain fields.
|
|
|
|
This can be controlled by:
|
|
|
|
| Flag | Default |Sample XML |
|
|
| -- | -- | -- |
|
|
| `--xml-attribute-prefix` | `+` (changing to `+@` soon) | Legs in ```<cat legs="4"/>``` |
|
|
| `--xml-content-name` | `+content` | Meow in ```<cat>Meow <fur>true</true></cat>``` |
|
|
| `--xml-directive-name` | `+directive` | ```<!DOCTYPE config system "blah">``` |
|
|
| `--xml-proc-inst-prefix` | `+p_` | ```<?xml version="1"?>``` |
|
|
|
|
|
|
{% hint style="warning" %}
|
|
Default Attribute Prefix will be changing in v4.30!
|
|
In order to avoid name conflicts (e.g. having an attribute named "content" will create a field that clashes with the default content name of "+content") the attribute prefix will be changing to "+@".
|
|
|
|
This will affect users that have not set their own prefix and are not roundtripping XML changes.
|
|
|
|
{% endhint %}
|
|
|
|
## Encoder / Decoder flag options
|
|
|
|
In addition to the above flags, there are the following xml encoder/decoder options controlled by flags:
|
|
|
|
| Flag | Default | Description |
|
|
| -- | -- | -- |
|
|
| `--xml-strict-mode` | false | Strict mode enforces the requirements of the XML specification. When switched off the parser allows input containing common mistakes. See [the Golang xml decoder ](https://pkg.go.dev/encoding/xml#Decoder) for more details.|
|
|
| `--xml-keep-namespace` | true | Keeps the namespace of attributes |
|
|
| `--xml-raw-token` | true | Does not verify that start and end elements match and does not translate name space prefixes to their corresponding URLs. |
|
|
| `--xml-skip-proc-inst` | false | Skips over processing instructions, e.g. `<?xml version="1"?>` |
|
|
| `--xml-skip-directives` | false | Skips over directives, e.g. ```<!DOCTYPE config system "blah">``` |
|
