Question

What is an XML parser. Name them .​

Answer 1

It means "reading" the XML file/string and getting its content according to the structure, usually to use them in a program.

For example if you have this XML fragment:

<root> <node1>value1</node1> <node2>value2</node2> </root>

you may want to use these values in a data structure:

ClassRoot: node1: string node2: string

so that, in the end:

Object goofy = ClassRoot.new parse(xml, goofy) puts(goofy)

yelds something like:

goofy[node1='value1'; node2='value2']

There are many ways of doing so, like DOM or SAX. You might want to investigate XSLTand xpath as well, according to your needs
