Examples

Extract the content of a single tag...

xml = parse_xml("""
<CreateQueueResponse>
    <CreateQueueResult>
        <QueueUrl>http://queue.amazonaws.com/123456789012/testQueue</QueueUrl>
    </CreateQueueResult>
</CreateQueueResponse>
""")

@test xml["CreateQueueResult"]["QueueUrl"] == "http://queue.amazonaws.com/123456789012/testQueue"

Extract an attribute from a tag by using a :symbol as key...

xml = parse_xml("""
<bookstore>
  <book category="COOKING" tag="first"/>
<bookstore>
""")

@test xml["bookstore"]["book"][:category] == "COOKING"

Extract a list of tag content...

xml = parse_xml("""
<ListAllMyBucketsResult>
  <Buckets>
    <Bucket><Name>quotes</Name><CreationDate>2006-02-03T16:45:09.000Z</CreationDate></Bucket>
    <Bucket><Name>samples</Name><CreationDate>2006-02-03T16:41:58.000Z</CreationDate></Bucket>
  </Buckets>
</ListAllMyBucketsResult>
""")

@test [b["Name"] for b in xml["Buckets"]["Bucket"]] == ["quotes", "samples"]

Extract a dictionary of <Name>, <Value> tags content...

xml = parse_xml("""
<GetQueueAttributesResponse>
  <GetQueueAttributesResult>
    <Attribute><Name>VisibilityTimeout</Name><Value>30</Value></Attribute>
    <Attribute><Name>CreatedTimestamp</Name><Value>1286771522</Value></Attribute>
    <Attribute><Name>MaximumMessageSize</Name><Value>8192</Value></Attribute>
    <Attribute><Name>MessageRetentionPeriod</Name><Value>345600</Value></Attribute>
  </GetQueueAttributesResult>
</GetQueueAttributesResponse>
""")

d = [a["Name"] => a["Value"] for a in xml["GetQueueAttributesResult"]["Attribute"]]

Dict with 4 entries:
  "MessageRetentionPeriod" => "345600"
  "MaximumMessageSize"     => "8192"
  "VisibilityTimeout"      => "30"
  "CreatedTimestamp"       => "1286771522"

Convert entire XML document to a Julia Dict...
