XML Attribute

An XML attribute is an identifier associated with an XML tag. It has a unique name in the context of the tag, and a string value. A tag can have any number of attributes, including none.

<tagNameattribName="Value">…</tagName>

<tagNameattribName="Value"/>

Conversion to Struct

An XML element converts to a Struct with the name attribName, and annotation tag xmlClass = attribute.

Annotations

The Struct for an XML element can have the following annotations:

xmlClass = attribute
xmlNamespaceURI = URI
xmlNamespaceAlias = prefix

If xmlToStruct/schema is used, and if the data type is defined in a schema with a namespace, it can have addition annotations:

xmlDataType =DataType
xmlTypeCategory = simple | complex
xmlTypeNamespace =

XML to Struct Conversion: Attributes

XML element with attribute and value:

<para audience="admin">text</para>

String returned by $dbgString after conversion:

[]
  [para]
    [$tags]
      [xmlClass] = element
    [aurience] = admin
      [$tags]
        [xmlClass] = attribute
    [] = text

You can get the values of Structs using Struct access operators. For example:

vValue = vStruct->p                              ; Result: vValue = "text"
vClass = vStruct->p->$tags->xmlClass             ; Result: vClass = "element"

vValue = vStruct->p->priority                    ; Result: vValue = "2"
vClass = vStruct->p->priority->$tags->xmlClass   ; Result: vClass = "attribute"
