htmlNode (Type of variable)
In french: htmlNoeud
The htmlNode type is used to define all the advanced characteristics of a node of an HTML document. The characteristics of this node can be defined and changed using different WLanguage properties.
Remark: For more details on the declaration of this type of variable and the use of WLanguage properties, see Declaring a variable.
MyDocument is htmlDocument
// Retrieves the document from the HTML Display control
MyDocument = HTM_Source.DisplayedValue
// Get delivery costs when choosing pickup points depending on the weight
// Get the countries
// In thead / 2nd TR / 3 first TD
sCountry1, sCountry2, sCountry3 is string
// Get array of headers
arrHeader is array of htmlNode = MyDocument.FindElementByTag("thead")
// On the first element, take the second child (second TR)
// The first child of this TR is the TD of the first country
// Inside the TD, there can be other tags (span, p) to manage styles
// But the final content is in there, so we can retrieve the InnerHTML from the TD, and
// Convert it "directly" to text
sCountry1 = HTMLToText(arrHeader[1].tr[2].td[1]..InnerHTML)
// The second child of this TR, is the TD of the second country
sCountry2 = HTMLToText(arrHeader[1].tr[2].td[2]..InnerHTML)
// The third child of this TR is the TD of the third country
sCountry3 = HTMLToText(arrHeader[1].tr[2].td[3]..InnerHTML)
sWeight, sPricingCountry1, sPricingCountry2, sPricingCountry3 are strings
// Modifies the table column titles
TABLE_Pricing.COL_Country1.Caption = sCountry1
TABLE_Pricing.COL_Country2.Caption = sCountry2
TABLE_Pricing.COL_Country3.Caption = sCountry3
FOR i = 1 _TO_ 9
// Get the weight and prices per country
sWeight =[i].td[1]..Text
sPricingCountry1 =[i].td[3]..Text
sPricingCountry2 =[i].td[4]..Text
sPricingCountry3 =[i].td[5]..Text
TABLE_Pricing.AddLine(sWeight, sPricingCountry1, sPricingCountry2, sPricingCountry3)

Properties specific to the description of htmlNode variables

The following properties can be used to handle a node of an HTML document:
Property nameType usedEffect
AttributeArray of htmlAttributeAttributes of an htmlNodeElement node.
ChildNodeArray of htmlNode variablesChild node of an htmlNodeElement node.
CountIntegerNumber of elements with the same name.
This property is read-only.
  • True if the node exists in the document,
  • False otherwise.
This property is read-only.
IndexIntegerIndex of the node in its parent.
This property is read-only.
InnerHTMLCharacter stringHTML code of the sub-nodes in the current node.
OuterHTMLCharacter stringHTML code that includes the current node (including the sub-node).
This property is read-only.
ParenthtmlNode variableParent node, NULL if the node is the root.
This property is read-only.
TagNameCharacter stringName of the tag if the node is an htmlNodeElement node, empty string ("") otherwise.
TextCharacter stringContents of the node encoded in the current character set.
  • If the node is of type htmlNodeText, htmlNodeComment or htmlNodeCDATA, the property returns and modifies the node.
  • If the node is of type htmlNodeElement, the property returns the concatenation of the text of all subnodes.
When a value is assigned to the property, it empties the subnodes and replaces them with a text subnode containing that value.
TypeInteger constantType of node:
  • htmlNodeComment: Comment node.
  • htmlNodeCDATA: CDATA Node (XHTML compatibility).
  • htmlNodeElement: Element node, HTML tag.
  • htmlNodeTexte: Text node.
The following operators are available for a node of type htmlNodeElement:
  • "." operator: The "." operator is used to access subelements by tag name.
  • ":" operator: The ":" operator is used to access attributes by name.
  • [ <index> ] operator: This operator is used to access sibling subelements of the same name by index.
  • [ <name> ] operator: This operator is used to access subelements by tag name.
htmlNodeElement nodes can contain subnodes.
Loop through subnodes
  • "FOR EACH x OF NodeVariable" is used to loop through all the subnodes.
  • "FOR EACH x OF NodeVariable IN-DEPTH" is used to recursively loop through all the subnodes.
