XML Builder
=======
[](https://travis-ci.org/joshnuss/xml_builder)
## Overview
An Elixir library for building xml.
Each xml node is structured as a tuple of name, attributes map and content/list:
```elixir
{name, attrs, content | list}
```
## Installation
Add dependency to your project's `mix.exs`
```elixir
def deps do
[{:xml_builder, "~> 0.1.1"}]
end
```
## Examples
### A simple element
Like `<person id="12345">Josh</person>`, would look like:
```elixir
{:person, %{id: 12345}, "Josh"} |> XmlBuilder.generate
```
### An element with child elements
Like `<person id="12345"><first>Josh</first><last>Nussbaum</last></person>`
```elixir
{:person, %{id: 12345}, [{:first, nil, "Josh"}, {:last, nil, "Nussbaum"}]} |> XmlBuilder.generate
```
### Convenience Functions
For more readability, you can use XmlBuilder's methods instead of creating tuples manually.
```elixir
XmlBuilder.doc(:person, "Josh")
```
Outputs
```xml
<?xml version="1.0" encoding="UTF-8" ?>
<person>Josh</person>
```
#### Building up an element
An element can be built using multiple calls to the `element` function
```elixir
import XmlBuilder
def person(id, first, last) do
element(:person, %{id: id}, [
element(:first, first),
element(:last, last)
])
end
iex> [person(123, "Steve", "Jobs"),
person(456, "Steve", "Wozniak")] |> generate
```
Outputs
```xml
<person id="123">
<first>Steve</first>
<last>Jobs</last>
</person>"
<person id="456">
<first>Steve</first>
<last>Wozniak</last>
</person>"
```
#### Using keyed lists
The previous example can be simplified using a keyed list
```elixir
import XmlBuilder
def person(id, first, last) do
element(:person, %{id: id}, first: first,
last: last)
end
iex> person(123, "Josh", "Nussbaum") |> generate
"<person id=\"123\"><first>Josh</first><last>Nussbaum</last></person>"
```
