XmlQuery

Some simple XML query functions. Delegates much of its work to :xmerl, but provides an API similar to HtmlQuery.

iex> alias XmlQuery, to: Xq

iex> xml = """
<?xml version="1.0"?>
<family>
  <child age="12" name="Alice" />
  <child age="9" name="Billy">
    <toys>
      <toy name="Voltron">
        <limb>Leg</limb>
        <animal>Lion</animal>
        <color>Blue</color>
      </toy>
    </toys>
  </child>
</family>
"""

iex> xml |> Xq.all("//child") |> Enum.map(&Xq.attr(&1, "age"))
["12", "9"]

iex> xml |> Xq.find!("//toy") |> Xq.text()
"Leg Lion Blue"

iex> xml |> Xq.find!("//toy/animal") |> Xq.text()
"Lion"
