Exercise 11-1

11.1. Conduct research on the Internet to find out what tools can be to parse an XML document and ensure that the document is well formed and valid.

W3schools(2009) states that all modern browsers have a built-in XML parser that can be used to read and manipulate XML, and the tools are used to ensure that XML document is well formed and valid such as
W3schools’s XML Validator (http://www.w3schools.com/xml/xml_validator.asp),
validome’s XML Validator (http://www.validome.org/xml/) and
PMC XML Validator (http://www.pubmedcentral.nih.gov/utils/validate/xmlcheck.cgi)
