Principle for handling an XML document

To manage an XML document, see Using an xmlDocument variable. This method allows you to use a XSD file.

Several types of specific variables are available:


xmlAttribute	The xmlAttribute type is used to handle the attributes of a node in an XML document.
xmlDocument	The xmlDocument type is used to handle an XML file.
xmlNamespace	The xmlNamespace type is used to handle the XML namespace of a node attribute in an XML document.
xmlNode	The xmlNode type is used to handle a node of an XML document.

Several specific functions can be used to handle the xmlDocument variables


<xmlDocument variable>.BuildString	Retrieves and formats the content of an XML document.
<xmlDocument variable>.ExecuteXPath	Executes an XPATH query in an xmlDocument variable.
<xmlDocument variable>.Save	Saves an XML document in a file.
<xmlDocument variable>.ValidDocument	Validates an XML document from an XSD schema.
<xmlNode variable>.FindNamespaceByName	Finds an XML namespace according to its XML node and in the parents of the node.
<xmlNode variable>.FindNamespaceByURI	Finds an XML namespace from its URI (Universal Resource Identifier) in a node and in the parents of this node.
<xmlNode variable>.ValidNode	Validates an XML node, its children and its attributes from its description in the XSD schema linked to the XML document.

Some functions are also linked to the management of XML:


<Source>.ExportXML	Exports the records found in a data file (HFSQL or OLE DB), view or query to an XML file.
<Source>.ImportXML	Imports an XML file into an HFSQL Classic or Client/Server data file (data file described in the data model editor or declared by <Source>.Declare, <Source>.DeclareExternal or <Source>.DescribeFile).
<Source>.RecordToXML	Retrieves the structure and the value of the current record and exports them into a character string in XML format.
J2EERunXML	Runs a procedure on a server of J2EE XML Web services.
<Looper>.ToXML	Creates an XML file with data from a Looper control (Looper control based on a data file or populated programmatically).
SOAPRunXML	Runs a procedure on a SOAP server.
<Table>.ToXML	Creates an XML file from the data found in a Table or TreeView Table control.

Training (WINDEV): WD Syntactic Coloring

[ + ] This example proposes a base class used to perform a standard syntax highlighting on some text.
This highlighting is based on a rough analysis of the lemmes found in a text in order to identify the elements of a programming language for instance.
It can be overridden or derived in order to customize the system and the highlighting language.
This example is used to highlight SQL code and XML code but it can be extended to highlight other languages or other text formats.
