May 27, 2020 The querystring.stringify method is used to produce an URL query string from the given object that contains the key-value pairs. The method iterates through the object’s own properties to generate the query string. It can serialize a single or an array of strings, numbers, and booleans. Any other types of values are coerced to empty strings. Mar 12, 2018 Node.js vs PHP — Technical Analysis. Let’s take a look at pros and cons of each technology. Native serialization and deserialization with.
At times, you may need to parse XML content and convert it into a DOM tree, or, conversely, serialize an existing DOM tree into XML. In this article, we'll look at the objects provided by the web platform to make the common tasks of serializing and parsing XML easy.
- Serializes DOM trees, converting them into strings containing XML.
- Constructs a DOM tree by parsing a string containing XML, returning a
Documentas appropriate based on the input data.
- Loads content from a URL; XML content is returned as an XML
Documentobject with a DOM tree built from the XML itself.
- A technology for creating strings that contain addresses for specific portions of an XML document, and locating XML nodes based on those addresses.
Creating an XML document
Using one of the following approaches to create an XML document (which is an instance of
Parsing strings into DOM trees
This example converts an XML fragment in a string into a DOM tree using a
Parsing URL-addressable resources into DOM trees
Here is sample code that reads and parses a URL-addressable XML file into a DOM tree:
The value returned in the
responseXML field is a
Document constructed by parsing the XML.
If the document is HTML, the code shown above will return a
Document. If the document is XML, the resulting object is actually a
XMLDocument. The two types are essentially the same; the difference is largely historical, although differentiating has some practical benefits as well.
Note: There is in fact an
HTMLDocument interface as well, but it is not necessarily an independent type. In some browsers it is, while in others it is simply an alias for the
Document Best news app for macos. interface.
Serializing an XML document
Document, you can serialize the document's DOM tree back into XML using the
Use the following approaches to serialize the contents of the XML document you created in the previous section.
Serializing DOM trees to strings
First, create a DOM tree as described in How to Create a DOM tree. Alternatively, use a DOM tree obtained from
To serialize the DOM tree
doc into XML text, call
Serializing HTML documents
If the DOM you have is an HTML document, you can serialize using
serializeToString(), but there is a simpler option: just use the
Element.innerHTML property (if you want just the descendants of the specified node) or the
Element.outerHTML property if you want the node and all its descendants.
As a result,
docHTML is a
DOMString containing the HTML of the contents of the document; that is, the
<body> element's contents.

You can get HTML corresponding to the
<body>and its descendants with this code:
