Syntax
<Result> = XMLData(<XML document> [, <Attribute> [, <Search mode>]])
<Result>: Character string - Value of current element or value of specified attribute.
- Empty string (""):
- if the current element has no value.
- if the specified attribute is not a child of the current element.
- if there is no current element. In this case, the ErrorOccurred variable is set to True. To get more details on the error, use ErrorInfo.
- if the current element is already an attribute. In this case, the ErrorOccurred variable is set to True. To get more details on the error, use ErrorInfo.
<XML document>: Character string Name of the XML document used. This document contains the XML code to study and it was created by XMLDocument. <Attribute>: Optional character string Name of child attribute of current tag for which the value must be returned. This attribute is sought among the direct children of current element. If this parameter is not specified (or if it corresponds to Null or an empty string), XMLData returns the value of the current tag. <Search mode>: Optional Integer constant Search mode use to find the attribute among the children of current element. | | | XMLContains | Search for the first attribute whose name contains the value of <Attribute>. | XMLExact
(Default value) | Search for the first attribute whose name exactly corresponds to the value of <Attribute>. | | XMLIgnoreCase | Search for the first attribute whose name corresponds to the value of <Attribute> regardless of the case.
Can be combined with the constants XMLContains, XMLStartWith or XMLExact. | | XMLStartWith | Search for the first attribute whose name starts with the content of <Attribute>. |
