Declaration

|---|---|---|---|---|
| ||||
TEXT %XML_GetElementText( INT in node, TEXT in element, [ TEXT in namespace := "" ] ) |
Parameters
| node | Handle to parent XML nod or XML list. |
| element | Name of element, from which a text is obtained. |
| namespace | Optional parameter that defines the name of namespace or prefix of an XML element. The value "*" is used, when there is not |
| the necessity to explicitly take into account namespace and the searching is done only by the element name. |
Return value
Description
The function returns a text string stored in an XML element, which is defined by the name of an element and a namespace or its prefix. If more than one element match the defined parameters, the function returns invalid value.
The searching is done recursively to the depth, therefore it is recommended to place the handle to a parent element as close as possible to the required XML element in the hierarchical XML structure. If the function returns an invalid result, you may find out the information about error by calling the function %XML_GetLastErrorMessage.
