Installing Xerces2 Java Parser for XSD 1.1
This section provides a quick introduction of Xerces2 and a tutorial of downloading and installing JAR files of Xerces2 Java Parser for XSD 1.1.
What Is Xerces2 Java Parser? Xerces2 Java Parser is an open source Java API of XML parsers. Xerces2 Java Parser supports XML standards, XInclude, DOM, SAX, JAXP, and XML Schema.
The current version of Xerces2 Java Parser is release 2.12.1, which supports the following standards and APIs:
Xerces2 has been included JDK since JDK 1.6 as the default JAXP API implementation. But the one included in JDK is definitely not the latest release of Xerces2. So you have 3 options to use Xerces2 to support XML, XSD and related technologies.
Since the Xerces2 code included in JDK 13 does not support XML Schema (XSD) 1.1, I want to download and install the latest version of Xerces2 to play with XSD 1.1 features. Here is what I did:
1. Go to the Xerces2 Java Parser home page at http://xerces.apache.org/xerces2-j/.
2. Click the link "Download" on the left, then click the "Binary Distributions" link.
3. Click the "Xerces2 Java 2.12.1 (XML Schema 1.1) - zip" link to start the download. Please do not select the regular version. It does not support XSD 1.1.
4. Save the downloaded file, Xerces-J-bin.2.12.1-xml-schema-1.1.zip, to your current working directory.
5. Unzip the downloaded file, Xerces2 JAR and other files will be located in the sub-directory, xerces-2_12_1:
