Modify tag contents

Description

Modify the contents (aka children) of a tag object.

Usage

tagAppendChild(tag, child, .cssSelector = NULL)

tagAppendChildren(tag, ..., .cssSelector = NULL, list = NULL)

tagSetChildren(tag, ..., .cssSelector = NULL, list = NULL)

tagInsertChildren(tag, after, ..., .cssSelector = NULL, list = NULL)

Arguments

tag

a tag object.

child

A child element to append to a parent tag.

.cssSelector

A character string containing a CSS selector for targeting particular (inner) tags of interest. At the moment, only a combination of type (e.g, div), class (e.g., .my-class), id (e.g., #myID), and universal (*) selectors within a given simple selector is supported. Note, if .cssSelector is used, the returned tags will have their $children fields flattened to a single list() via tagQuery().

...

a collection of child elements.

list

Deprecated. Use !!! instead to splice into ....

after

an integer value (i.e., subscript) referring to the child position to append after.
