# do-append-xml-text

The <do-append-xml-text> action causes the text provided by <arg-string> to be appended to the set of elements selected by expression. If before is not specified the text is appended after any existing children of the selected elements. If before is specified then it is evaluated relative to each of the elements selected by expression to determine which of the children to insert before. If before evaluates to an empty nodeset or a nodeset that does not contain any children of the selected element, then the text is appended after any existing children, otherwise the text will be inserted before each of the nodes in the nodeset selected by before that are children of the selected node.
