- Creating a text node
- WLanguage functions that use htmlNode variables
The htmlNode type is used to define all the advanced characteristics of a node of an HTML document. You can define and change the characteristics of this node using different WLanguage properties. Note: 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 = MyDocument.html.body.div.div.table.tbody.tr[i].td[1]..Text
sPricingCountry1 = MyDocument.html.body.div.div.table.tbody.tr[i].td[3]..Text
sPricingCountry2 = MyDocument.html.body.div.div.table.tbody.tr[i].td[4]..Text
sPricingCountry3 = MyDocument.html.body.div.div.table.tbody.tr[i].td[5]..Text
TABLE_Pricing.AddLine(sWeight, sPricingCountry1, sPricingCountry2, sPricingCountry3)

To describe an HTML node, the name of the node can be specified with the TagName property. <Tag name>: Character string Name of the node to create. Propiedades Properties specific to htmlNode variables The following properties can be used to handle a node of an HTML document: | | | | Property name | Type used | Effect |
|---|
| Attribute | Array of htmlAttribute | Attributes of an htmlNodeElement node. | | ChildNode | Array of htmlNode variables | Child node of an htmlNodeElement node. | | Count | Integer | Number of elements with the same name. This property is read-only. | | Exist | Boolean | - True if the node exists in the document,
- False otherwise.
This property is read-only. | | Index | Integer | Index of the node in its parent. This property is read-only. | | InnerHTML | Character string | HTML code of the sub-nodes in the current node. | | OuterHTML | Character string | HTML code that includes the current node (including the sub-node). This property is read-only. | | Parent | htmlNode variable | Parent node, NULL if the node is the root. This property is read-only. | | TagName | Character string | Name of the tag if the node is an htmlNodeElement node, empty string ("") otherwise. | | Text | Character string | Contents 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. | | Type | Integer constant | Type of node: - htmlComment node Comment node.
- htmlNodeCDATA CDATA node (XHTML compatible).
- htmlElementNode Element node, a tag in HTML.
- htmlTextNode Text node.

Observaciones The following operators are available for a node of type htmlNodeElement: - Operator ".": The operator "." allows access to sub-elements by their tag name.
- Operator ":": The ":" operator is used to access attributes by name.
- Operator [ <indice> ]: This operator is used to access sibling sub-elements of the same name by their index.
- Operator [ <nom> ]: This operator is used to access sub-elements by their tag name.
htmlNodeElement nodes can contain subnodes. Looping 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.
Creating a text node A text node can be declared using one of the following syntaxes: - Implicit declaration:
o is htmlNode
o.Text = "A" - Explicit declaration:
o is htmlNode
o.Type = htmlNodeText
o.Text = "A"
WLanguage functions that use htmlNode variables - standard syntax:
| | | HTMLFindElementByClass | Searches for elements whose "class" attribute matches a specific value in an HTML document (or in an HTML node). | | HTMLFindElementByID | Busca el elemento cuyo atributo "ID" coincide con un valor específico en un documento HTML (o en un nodo HTML). | | HTMLFindElementByName | Searches for elements whose "name" attribute matches a specific value in an HTML document (or in an HTML node). | | HTMLFindElementByTag | Searches for elements that correspond to a tag in an HTML document (or an HTML node). | | HTMLInsertAfter | Adds a node after the specified node in an HTML document. | | HTMLInsertBefore | Adds a node before the specified node in an HTML document. | | HTMLInsertFirstChild | Añade un hijo al principio de los hijos del nodo actual en un documento HTML. | | HTMLInsertLastChild | Adds a child after the child of the current node in an HTML document. | | HTMLModifyAttribute | Adds or changes an attribute of the current node of the HTML document. | | HTMLRemove | Removes the specified node and its descendants in an HTML document. | | HTMLRemoveAttribute | Elimina un atributo determinado | | HTMLRemoveChild | Removes a given node in the current node of an HTML document. | | HTMLUnwrapAllChildren | Elimina el nodo especificado en un documento HTML sin eliminar sus hijos, que ocupan su lugar. | | HTMLWrap | Wraps the specified node in a given node of an HTML document. | | HTMLWrapAllChildren | Envuelve todos los hijos del nodo dado en un nuevo nodo en un documento HTML.. |
