Description Example of php.js unserialize function: In the following web document, unserialize function converts a serialize data to actual format. When your lamba expression is executed the cm (short for class map) parameter is passed an empty class map for you to fill in. In this example two properties are added to the class map by calling the MapProperty method. The arguments to MapProperty are themselves lambda expressions which identify the property of the class. The advantage of using a lambda expression instead of just a string. The method JSON.stringify can accept at the most two arguments, in addition to the object being serialized, these arguments are used to specify alternate ways to serialize a JavaScript Object. The first argument is filter, which can be either a function or an array.

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.

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.

XMLSerializer
Serializes DOM trees, converting them into strings containing XML.
DOMParser
Constructs a DOM tree by parsing a string containing XML, returning a XMLDocument or Document as appropriate based on the input data.
XMLHttpRequest
Loads content from a URL; XML content is returned as an XML Document object with a DOM tree built from the XML itself.
XPath
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 Document.

Parsing strings into DOM trees

This example converts an XML fragment in a string into a DOM tree using a DOMParser:

Parsing URL-addressable resources into DOM trees

Using XMLHttpRequest

Here is sample code that reads and parses a URL-addressable XML file into a DOM tree:

The value returned in the xhr object's 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

Given a Document, you can serialize the document's DOM tree back into XML using the XMLSerializer.serializeToString() method.

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 XMLHttpRequest.

To serialize the DOM tree doc into XML text, call XMLSerializer.serializeToString():

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.

Js Serialize Object

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