The function returns a text string stored in XML element.
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 XML element. The value "*" is used, when there is not
necessary 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 XML element,
which is defined by the name of element and 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.
Example
TEXT _errorCodeText
TEXT _text
_text := %XML_GetElementText(_doc,"td","h")
IF (!_text\VLD) THEN
_errorCodeText := %XML_GetLastErrorMessage()
ENDIF
