simpleXMLParser

simpleXMLParser is a library written in Kotlin lang that can be used to convert XML into Java/Kotlin Objects representation. It can also be used to convert an XML string to an equivalent Java/Kotlin object.

The library requires to mark data class and each field which should be parsed with annotation @XMLName or @XMLAsArray.

simpleXMLParser Goals

• Provide simple parse() methods to convert input stream with XML or string into Java/Kotlin objects;
• Provide a mechanism to parse elements with the same name into one array (could be usefull for parsing RSS feeds, to be exact 'item' elements)
• Allow custom representations for objects;
• Support arbitrarily complex objects (with deep inheritance hierarchies and extensive use of generic types);
• Simple installation by downloading via gradle;

simpleXMLParser Documentation

simpleXMLParser API:

The main class SimpleXmlParser.kt. It contains 2 methods in Companion object:

fun <T> parse(input: InputStream?, clazz: Class<T>): T?

fun <T> parse(input: String?, clazz: Class<T>): T?

Usage

Kotlin code:

var entry = SimpleXmlParser.parse(input, TestEntry::class.java!!)

Java code:

TestEntry entry = SimpleXmlParser.Companion.parse(input, TestEntry.class);

TestEntry class could be like:

Kotlin code:

Can be used with data class (in current version constructor params should have default value. The library needs default constructor in class)

@XmlName(name = "item")
data class TestEntry(@XmlName(name = "title") var title: String = "",
    @XmlName(names = *arrayOf("content:encoded", "description")) var description: String = "")

Also can be used with regular classes:

@XmlName(name = "item")
class TestEntry {
    @XmlName(name = "title") var title: String? = null
    @XmlName(names = *arrayOf("content:encoded", "description")) var description: String? = null
}

Java code:

@XmlName(name = "channel")
public class TestEntry {
    @XmlName(name = "title")
    public String title;
    @XmlAsArray(name = "item")
    public ArrayList<FeedEntryWithAnnotation> items = new ArrayList<>();
}
