### Main Features
|
||
|
||
<img align="right" src="static/img/fxp_logo.png" width="180px" alt="FXP logo"/>
|
||
|
||
* Validate XML data syntactically
|
||
* Transform XML to JSON or Nimn
|
||
* Transform JSON back to XML
|
||
* Works with node packages, in browser, and in CLI (press try me button above for demo)
|
||
* Faster than any pure JS implementation.
|
||
* It can handle big files (tested up to 100mb).
|
||
* Various options are available to customize the transformation
|
||
* You can parse CDATA as separate property.
|
||
* You can prefix attributes or group them to separate property. Or can ignore them from result completely.
|
||
* You can parse tag's or attribute's value to primitive type: string, integer, float, hexadecimal, or boolean. And can optionally decode for HTML char.
|
||
* You can remove namespace from tag or attribute name while parsing
|
||
* It supports boolean attributes, if configured.
|
||

## How to use
|
||
|
||
To use it in **NPM package** install it first

|
||
|
||
### XML to JSON
|
||
|
||
|
||
```js
|
||
var jsonObj = parser.parse(xmlData [,options] );
|
||
```
|
||
|
||
```js
|
||
var parser = require('fast-xml-parser');
|
||
var he = require('he');
|
||
|
||
var options = {
|
||
attributeNamePrefix : "@_",
|
||
attrNodeName: "attr", //default is 'false'
|
||
textNodeName : "#text",
|
||
ignoreAttributes : true,
|
||
ignoreNameSpace : false,
|
||
allowBooleanAttributes : false,
|
||
parseNodeValue : true,

||
parseAttributeValue : false,
|
||
trimValues: true,
|
||
cdataTagName: "__cdata", //default is 'false'
|
||
cdataPositionChar: "\\c",
|
||
localeRange: "", //To support non english character in tag/attribute values.
|
||
parseTrueNumberOnly: false,
|
||
attrValueProcessor: a => he.decode(a, {isAttributeValue: true}),//default is a=>a
|
||
tagValueProcessor : a => he.decode(a) //default is a=>a
|
||
};
|
||
|
||
if( parser.validate(xmlData) === true) { //optional (it'll return an object in case it's not valid)
|
||
var jsonObj = parser.parse(xmlData,options);
|
||
}
|
||
|
||
// Intermediate obj
|
||
var tObj = parser.getTraversalObj(xmlData,options);
|
||
var jsonObj = parser.convertToJson(tObj,options);
|
||
|
||
```
|
||
#### Note: [he](https://www.npmjs.com/package/he) library is used in this example

<details>
|
||
<summary>OPTIONS :</summary>
|
||
|
||
* **attributeNamePrefix** : prepend given string to attribute name for identification
|
||
* **attrNodeName**: (Valid name) Group all the attributes as properties of given name.
|
||
* **ignoreAttributes** : Ignore attributes to be parsed.
|
||
* **ignoreNameSpace** : Remove namespace string from tag and attribute names.
|
||
* **allowBooleanAttributes** : a tag can have attributes without any value
|
||
* **parseNodeValue** : Parse the value of text node to float, integer, or boolean.
|
||
* **parseAttributeValue** : Parse the value of an attribute to float, integer, or boolean.
|
||
* **trimValues** : trim string values of an attribute or node
|
||
* **decodeHTMLchar** : This options has been removed from 3.3.4. Instead, use tagValueProcessor, and attrValueProcessor. See above example.
|
||
* **cdataTagName** : If specified, parser parse CDATA as nested tag instead of adding it's value to parent tag.
|
||
* **cdataPositionChar** : It'll help to covert JSON back to XML without losing CDATA position.
|
||
* **localeRange**: Parser will accept non-English character in tag or attribute name. Check #87 for more detail. Eg `localeRange: "a-zA-Zа-яёА-ЯЁ"`
|
||
* **parseTrueNumberOnly**: if true then values like "+123", or "0123" will not be parsed as number.
|
||
* **tagValueProcessor** : Process tag value during transformation. Like HTML decoding, word capitalization, etc. Applicable in case of string only.
|
||
* **attrValueProcessor** : Process attribute value during transformation. Like HTML decoding, word capitalization, etc. Applicable in case of string only.
|
||
* **stopNodes** : an array of tag names which are not required to be parsed. Instead their values are parsed as string.

```
|

### JSON / JS Object to XML
|
||
|
||
```js
|
||
var Parser = require("fast-xml-parser").j2xParser;
|
||
//default options need not to set
|
||
var defaultOptions = {
|
||
attributeNamePrefix : "@_",
|
||
attrNodeName: "@", //default is false
|
||
textNodeName : "#text",
|
||
ignoreAttributes : true,
|
||
cdataTagName: "__cdata", //default is false
|
||
cdataPositionChar: "\\c",
|
||
format: false,
|
||
indentBy: " ",
|
||
supressEmptyNode: false,
|
||
tagValueProcessor: a=> he.encode(a, { useNamedReferences: true}),// default is a=>a
|
||
attrValueProcessor: a=> he.encode(a, {isAttributeValue: isAttribute, useNamedReferences: true})// default is a=>a
|
||
};
|
||
var parser = new Parser(defaultOptions);
|
||
var xml = parser.parse(json_or_js_obj);
|
||
```
|
||
|
||
<details>
|
||
<summary>OPTIONS :</summary>
|
||
|
||
With the correct options, you can get the almost original XML without losing any information.
|
||
|
||
* **attributeNamePrefix** : Identify attributes with this prefix otherwise treat them as a tag.
|
||
* **attrNodeName**: Identify attributes when they are grouped under single property.
|
||
* **ignoreAttributes** : Don't check for attributes. Treats everything as tag.
|
||
* **encodeHTMLchar** : This option has been removed from 3.3.4. Use tagValueProcessor, and attrValueProcessor instead. See above example.
|
||
* **cdataTagName** : If specified, parse matching tag as CDATA
|
||
* **cdataPositionChar** : Identify the position where CDATA tag should be placed. If it is blank then CDATA will be added in the last of tag's value.
|
||
* **format** : If set to true, then format the XML output.
|
||
* **indentBy** : indent by this char `when` format is set to `true`
|
||
* **supressEmptyNode** : If set to `true`, tags with no value (text or nested tags) are written as self closing tags.
|
||
* **tagValueProcessor** : Process tag value during transformation. Like HTML encoding, word capitalization, etc. Applicable in case of string only.
|
||
* **attrValueProcessor** : Process attribute value during transformation. Like HTML encoding, word capitalization, etc. Applicable in case of string only.

### Limitations
|
||
Currently FXP fails to parse XML with attributes has ">" in the value. This problem is left open as change in regex for its fix is degrading the performance. And the parser become very slow in case of long attrbute names.
|
||
|
||
### Worth to mention
|
||
|
||
- **[BigBit standard)](https://github.com/amitguptagwl/bigbit)** : A standard to reprent any number in the universe in comparitively less space and without precision loss. A standard to save space to represent any text string in comparision of UTF encoding.
|
||
- **[imglab](https://github.com/NaturalIntelligence/imglab)** : Speedup and simplify image labeling / annotation. Supports multiple formats, one click annotation, easy interface and much more. There are more than 20k images are annotated every month.
|
||
- **[अनुमार्गक (anumargak)](https://github.com/NaturalIntelligence/anumargak)** : The fastest and simple router for node js web frameworks with many unique features.
|
||
- [stubmatic](https://github.com/NaturalIntelligence/Stubmatic) : A stub server to mock behaviour of HTTP(s) / REST / SOAP services, incuding DynamoDB calls. You can also mock binary formats.
|
||
- [मुनीम (Muneem)](https://github.com/muneem4node/muneem) : A webframework made for all team members. Faster tha fastify, express, koa, hapi and others.
|
||
- [शब्दावली (shabdawali)](https://github.com/amitguptagwl/shabdawali) : Amazing human like typing effects beyond your imagination.
