Discussion
%XML_ELEM_GETTEXT returns the text that appears between the specified element’s opening tag and closing tag, including any embedded XML documents delimited by CDATA. To control whether text or attribute values are escaped or unescaped, use the ENCODE option of %XML_OPTION. To control whether leading and trailing blanks are stripped in the text element, use the PARSER option of %XML_OPTION. (See %XML_OPTION.)
This function is defined as ^VAL.

If you want to receive variable-length data in a large buffer, we recommend using the length argument, as this will avoid time spent clearing the remainder of the buffer (beyond length) with spaces. |
