HImportXML (Function)
  Disponible solo con estos tipos de conexión
Imports an XML file into an HFSQL Classic or Client/Server data file. This data file must have been defined in the data model editor, or declared with HDeclare, HDeclareExternal or HDescribeFile). Sintaxis
<Result> = HImportXML(<Data file> [, <Path of the XML file> , <Destination items> [, <XML attributes to import>]] [, <Options> [, <Progress Bar> [, <Root node>]]])
<Result>: Boolean - True if the operation was performed,
- False if an error occurs. HError is used to identify the problem.
<Data file>: Character string Name of the HFSQL data file to import into. <Path of the XML file>: Optional character string Full access path to XML file to import. <Destination items>: Optional character string List of names of items in the data file into which the import will be performed. Names can be delimited by single quotes and are separated by commas or CR characters. The names of the composite key items, binary memo items and binary items are ignored.
The non-imported items will be initialized with their default value described in the analysis.
If this parameter is not specified or if it is an empty string, all the items are imported (except the composite keys, the binary items and the binary memos) in the physical order of description. <XML attributes to import>: Optional character string List of names of items found in the XML file to import.
If this parameter is not specified or if it corresponds to an empty string, all the nodes of XML files are imported. <Options>: Optional Integer constant (or combination of constants) Configures the type of import to perform: | | | hImpBreakable | The import can be interrupted by pressing the Esc key on the keyboard.
If the import is interrupted, the imported records are kept in the data file. | | hImpCreation | If the data file to import into exists, it will be overwritten. | hImpNormal
(default value) | If the import data file already exists, it is populated with the imported data; otherwise, the data file is created. |
<Progress Bar>: Optional control or window name - Name of the window in which the progress bar will be displayed
- Name of the Progress Bar control.
<Root node>: Optional character string Node of XML file from which the import will be performed. Used to import a section of XML file into the HFSQL data file. The type of this parameter is "root/clients". Observaciones Array items HImportXML can also be used to import array items. To do so, the array elements must be included in the child tags. Example The data file described in the analysis contains the following fields: RUB1, RUB2, RUBTABLE. The ARRAYITEM item is an array item. The list of items is "ITEM1+ITEM2+ARRAYITEM" and the XML file has the following structure: <FILE>
<ITEM1>Data1</ITEM1>
<ITEM2>Data2</ITEM2>
<ARRITEM>
<!-- child tags -->
<ARRAYITEM_1>ArrayData1</ARRAYITEM_1>
<ARRAYITEM_2>ArrayData2</ARRAYITEM_2>
</ARRITEM>
</FILE>
... 'Data1' will be assigned to 'ITEM1', 'Data2' will be assigned to 'ITEM2', 'ArrayData1' will be assigned to 'ARRAYITEM[1]', 'ArrayData2' will be assigned to ARRAYITEM[2]'. Format of expected XML HImportXML expects an XML file with a specific structure. Example: <racine><?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
<record>
<item1>val</item1>
<item2>val</item2>
</record>
<record>
<item1>val</item1>
<item2>val</item2>
</record>
</root> This format is also used by HExportXML. If your XML file does not use this structure, the import will not be performed properly. You may get one record per item for example. Clasificación Lógica de negocio / UI: Lógica de negocio
