Final bookshelfXml = ' Growing a Language 29.99 Learning XML 39.95 132.00 ';final document = xml. Parse(bookshelfXml);The resulting object is an instance of XmlDocument. In case the document cannot be parsed, a XmlParserException is thrown.To write back the parsed XML document simply call toString, if you need more control toXmlString(petty: true, indent: 't'). ToXmlString(pretty: true, indent: ' t')); Traversing and QueryingAccessors allow to access nodes in the XML tree:. attributes returns a list over the attributes of the current node.
children returns a list over the children of the current node.Both lists are mutable and support all common List methods, such as add(XmlNode), addAll(Iterable), insert(int, XmlNode), and insertAll(int, Iterable). Trying to add a null value or an unsupported node type throws an XmlNodeTypeError error. Nodes that are already part of a tree are not automatically moved, you need to first create a copy as otherwise an XmlParentError is thrown. XmlDocumentFragment nodes are automatically expanded and copies of their children are added.There are various methods to traverse the XML tree along its axes:. preceding returns an iterable over nodes preceding the opening tag of the current node in document order.
MindFusion's XML Viewer is used to examine the contents of an XML file in an easy-to-use environment. In addition you can make modification to the XML such as inserting and deleting nodes as well. StarUML is an open source project to develop fast, flexible, extensible, featureful, and freely-available UML/MDA platform running on Win32 platform. The goal is a compelling replacement of commercial UML tools such as RationalRose, Together and so on.
descendants returns an iterable over the descendants of the current node in document order. This includes the attributes of the current node, its children, the grandchildren, and so on. following the nodes following the closing tag of the current node in document order. ancestors returns an iterable over the ancestor nodes of the current node, that is the parent, the grandparent, and so on. Note that this is the only iterable that traverses nodes in reverse document order.For example, the descendants iterator could be used to extract all textual contents from an XML tree. Final total = document. FindAllElements( 'book').
Map((node) = double. FindElements( 'price').single.text)). Reduce((a, b) = a + b);print(total);Note that this first finds all the books, and then extracts the price to avoid counting the price tag that is included in the bookshelf.
BuildingWhile it is possible to instantiate and compose XmlDocument, XmlElement and XmlText nodes manually, the XmlBuilder provides a simple fluent API to build complete XML trees. To create the above bookshelf example one would write. Map((event) = event.text. Where((text) = text.isNotEmpty). Final url = Uri. Parse( 'request = await httpClient. GetUrl(url);final response = await request.
