Version 8.0.1
The abstract Node class

All classes of QF-Test's pseudo DOM are derived from this class and thus implement the following interface. Its is located in the package de.qfs.apps.qftest.client.web.dom.

 
 
Node findCommonAncestor(Node node1, Node node2, Node topmost)
Get the common parent of two nodes.
Parameters
node1The first node.
node2The second node.
topmostThe topmost node to stop the search.
ReturnsThe common parent or null.
 
Node getAncestorOfClass(String clazz)
Get the closest parent of a specified class name.
Parameters
clazzThe parent's class name.
ReturnsThe parent or null.
 
Node getAncestorOfClass(String clazz, int maxDepth)
Get the closest parent of a specified class name. You can specify a maximal search level.
Parameters
clazzThe parent's class name.
maxDepthThe maximum search level.
ReturnsThe parent or null.
 
String getAttribute(String name)
Get the value of an attribute of the node. For convenience this method is defined at Node level. If this node is not a DomNode the result will always be null. In some cases this method also returns attributes that have not been explicitly specified, like the width and height of an <IMG> node. Which attributes can be retrieved in that way is browser dependent.
Parameters
nameThe name of the attribute
Returns The value of the attribute or null if no such attribute is available for the node.
 
String getAttributeIfSpecified(String name)
Get the value of an attribute of the node if it is explicitly specified in the HTML code. For convenience this method is defined at Node level. If this node is not a DomNode the result will always be null.
Parameters
nameThe name of the attribute
Returns The value of the attribute or null if no such attribute is explicitly specified for the node.
 
Node getChild(int index)
Get the child node at the given index. Remark for Opera before version 86, Google Chrome and Microsoft Edge before version 100: Text-nodes, which are only used to format the HTML code and which have no influence on the visualisation of the web site are not transferred from the browser to QF-Test in CDP connection mode. Therefore, a different index of the child node can occure in this connection mode wth these browsers. If possible, use getChildrenByTagName in your scripts.
Parameters
indexThe index of the child node, starting with 0.
ReturnsThe child node at the index.
Throws
IllegalArgumentException If index is negative or exceeds the number of child nodes.
 
int getChildCount()
Get the number of child nodes. Remark for Opera before version 86, Google Chrome and Microsoft Edge before version 100: Text-nodes, which are only used to format the HTML code and which have no influence on the visualisation of the web site are not transferred from the browser to QF-Test in CDP connection mode. Therefore, a different number of the child nodes can occure in this connection mode with these browsers.
ReturnsThe number of child nodes.
 
Node[] getChildren()
Get the children of this node as an array. Remark for Opera before version 86, Google Chrome and Microsoft Edge before version 100: Text-nodes, which are only used to format the HTML code and which have no influence on the visualisation of the web site are not transferred from the browser to QF-Test in CDP connection mode. Therefore, less children might be reported in this connection mode with these browsers.
ReturnsThe child nodes.
 
String getClassName()
Get the most current class name of that node.
ReturnsThe most current class name.
 
String[] getClassNames()
Get all class names of that node.
ReturnsAn array with all class names of that node.
 
DocumentNode getDocument()
Get the document to which this node belongs.
Returns The document to which this node belongs. A DocumentNode will return itself, a DialogNode will return null.
 
Node getElementById(String id)
Get a direct or indirect child node of this node with a given ID. The given ID is not compared to the node's original 'ID' attribute, but to its ID, which may have been modified by an IdResolver (see subsection 53.1.17).
Parameters
idThe ID to look for.
Returns The child node with the given ID, an arbitrary one in case of multiple matches or null if none is found. A DialogNode will always return null, a FrameNode forwards the call to its DocumentNode child node and a DocumentNode to its <HTML> root element.
 
Node[] getElementsByClassName(String className)
Get all direct and indirect child nodes with a specified class.
Parameters
classNameThe name of the class.
ReturnsAn array of child nodes with the specified class name. If none are found, an empty array is returned.
 
Node[] getElementsById(String id)
Get all direct or indirect child nodes of this node with a given ID. The given ID is not compared to the node's original 'ID' attribute, but to its ID, which may have been modified by an IdResolver (see subsection 53.1.17).
Parameters
idThe ID to look for.
Returns An array of child nodes with the given ID. If none are found, an empty array is returned. A DialogNode will always return an empty array, a FrameNode forwards the call to its DocumentNode child node and a DocumentNode to its <HTML> root element.
 
Node[] getElementsByIdAndTagname(String id, String tagName)
Get all direct or indirect child nodes of this node with a given ID and a given tag name. The given ID is not compared to the node's original 'ID' attribute, but to its ID, which may have been modified by an IdResolver (see subsection 53.1.17).
Parameters
idThe ID to look for.
tagNameThe tag name to look for.
Returns An array of child nodes with the given ID and the given tag name. If none are found, an empty array is returned. A DialogNode will always return an empty array, a FrameNode forwards the call to its DocumentNode child node and a DocumentNode to its <HTML> root element.
 
Node[] getElementsByTagName(String tagName)
Get all direct or indirect child nodes of this node with a given tag name.
Parameters
tagNameThe tag name to look for.

ReturnsThe first child node.
 
Node getFirstElementChild()
Get the first child element (text nodes and comments are skipped).
ReturnsThe first child element.
