JS Date Range Picker is a package to let the user pick a range between two dates. It can be used to present two form inputs that let the user choose dates using calendar pull down menus. The dates may be validated so the range end date is not set to a day before the range start date. The format of the dates and the week start day are configurable parameters. The chosen dates are returned in the ISO-8601 extended format.
JS Merge XML is a class that merges XML documents from strings, DOM objects, or input files. It can take an XML document from a string or a DOM object tree, or a file taken from a form input and merges with another XML document. The resulting document can be searched using an XPath query string or returned as a string or a DOM object. It provides options to control whether the nodes with the same path or name are replaced or added sequentially.
