entity_expand
entity_expand (value[, flags[, doc]])
This function expands character and text entity references in the given value string and returns the expanded string.
• value is the value to be expanded
• flag is a bitmask that controls the expansion of the entity:
◦ 0x01 — expand character entity references
◦ 0x02 — expand text entity references
If omitted, the default is to expand all types of entity references.
• doc is the document which defines the entities. If omitted, the current document is used.
In XML the < and & characters must be escaped inside an attribute value; for example, in an attribute value, the string A<B&C>D should be encoded as A<&C.D.
To get the expanded value of the src attribute on the tag containing the caret:
local expandedValue = entity_expand( oid_attr( oid_caret(), 'src' ) )
