# Xml

The Xml module enables parsing information stored in local or remote xml files.

Requires Manatee v1.29 or greater

This version of the Xml module cannot be used with Manatee v1.28 or earlier.

# Load xml

Parse the given string as xml and return an XmlDoc object which can be queried or turned into JSON.

# Parameters

  • xml an xml formatted string to parse

# Example

var d = Xml.load("<hello>world</hello>");

# Load XML from url

Fetch a local or a remote file and parse as xml. Returns an XmlDoc object.

# Parameters

  • url is a local or remote path to an xml file

# Example

// A remote file
var remote = Xml.loadFrom("http://somewhere/over/the/rainbow.xml");
// A local file
var local = Xml.loadFrom("c:\\somewhere\over\the\rainbow.xml");

# Load XML from JSON string

You can use the loadJson function to parse a JSON string into an XmlDoc object. It should have the same structure as the output of the Xml.toJson function.

var json = JSON.stringify({ a: { b: 2 }, c: 3 }); 
var doc = Xml.loadJson(json);

# XmlDoc

An XmlDoc is an object that wraps an xml document and which has a few functions for querying the underlying document.

# XPath

Execute an XPath (opens new window) query and return the results. The result is a list of objects, each object represents the matching xml node.

# Parameters

# Example

var doc = Xml.load("<hello>world</hello>");
var allHellos = doc.xpath("//hello");

# Xml to JSON

Returns a JSON/JavaScript version of the document which can then be inspected in the flow.

# Example

var doc = Xml.load("<hello>world</hello>");
var docObject = doc.json();

# XmlDoc to XML string

Use the toString function to return the xml document as a string.

var doc = Xml.load("<hello>world</hello>");
var xmlString = doc.toString(); // "<hello>world</hello>"

# Modify an XML document

The walk function implements a visitor-pattern for the underlying xml document. It can be used to modify the document. You supply it with a function that may either return a new value as an object or xml string or a boolean value where false indicates that the node should be removed. The function will get called for each node in the document.

var doc = Xml.load("<root><hello>world</hello></root>");
doc.walk(function(node) {
    if (node.hello) {
        return "<hello>universe</hello>";
    }
});
var greeting = doc.toString(); // <root><hello>universe</hello></root>
