Methods

Name	Description

MoveBefore(Node, Node?)	Moves the node, preserving its state, before the given child (or to the end when the child is null).
Prepend(ReadOnlySpan<NodeOrString>)	Inserts the nodes before the first child, converting the strings into text nodes.
QuerySelector(SelectorList)	Returns the first descendant element, in tree order, that matches the parsed selector list, or null.
QuerySelector(string)	Returns the first descendant element, in tree order, that matches the selectors, or null.
QuerySelector<T>(SelectorList)	Returns the first descendant, in tree order, that is a `T` and matches the parsed selector.
QuerySelector<T>(string)	Returns the first descendant, in tree order, that is a `T` and matches the selector.
QuerySelectorAll(SelectorList)	Returns the descendant elements, in tree order, that match the parsed selector list.
QuerySelectorAll(string)	Returns the descendant elements, in tree order, that match the selectors.
QuerySelectorAll<T>(SelectorList)	Returns the descendants, in tree order, that are a `T` and match the parsed selector.
QuerySelectorAll<T>(string)	Returns the descendants, in tree order, that are a `T` and match the selector.
ReplaceChildren(ReadOnlySpan<NodeOrString>)	Replaces all the children with the given nodes, converting the strings into text nodes.

Append(ReadOnlySpan<NodeOrString>)

Inserts the nodes after the last child, converting the strings into text nodes.

public void MoveBefore(Node node, Node? child)

Parameters

node Node
child Node?

Prepend(ReadOnlySpan<NodeOrString>)

Inserts the nodes before the first child, converting the strings into text nodes.
