XML Path Language (XPath), one of the most successful XML technologies, is a syntax and data model for addressing parts of an XML document. XPath includes over 100 built-in functions. There are functions for string values, numeric values, date and time comparison, node and QName manipulation, sequence manipulation, Boolean values, and more. XPath was designed to be used by XSLT, XPointer and other XML parsing software.

I have to work on XSLT. Do I have to know about XPath first for that?

XPath is a major element in the XSLT standard. Without XPath knowledge you will not be able to create XSLT documents.

I am working with DB2 database and want to learn Xquery. I have some experience with XPath. Will it be helpful in learning Xquery?

XQuery 1.0 and XPath 2.0 share the same data model and support the same functions and operators. If you have already studied XPath you will have no problems with understanding XQuery.

Use xmlquery scalar function to return XML value
select xmlquery('$n/doc[make = "Honda"]' passing po.appl_doc as "n") AS
"Result" FROM loan_application po;

These are W3 supported XPath syntaxes.
i) / = Represents the
XML root element.
ii) /tag1 = Represents the
element tag1 under root.
iii) /tag1/tag2/.../tagn = Represents an element with the
name tagn as the child of the descending chain from root, tag1, tag2,
through tagn-1.
iv) //tagn Represents any
element with the name tagn, where the double slashes denote zero or more
arbitrary tags.
v) /tag1//tagn Represents any element with
the name tagn, a child of an element with name
tag1 under root, where double slashes denote zero or more arbitrary tags.
vi) /tag1/tag2[tag3="5"] Represents an
element with the name tag3 has the value 5. tag3 is a child of an element
with name tag2 under tag1 and root.
vii) /tag1/tag2/@attr1 Represents the attribute attr1 of
an element tag2, which is a child of element tag1 under root.
viii) /tag1/tag2[@attr1="5"] Represents an element with the name tag2
whose attribute attr1 has the value 5. tag2 is a child of an element with
name tag1 under root.
ix)/tag1/tag2[@attr1="5"]/.../tagn Represents an element with the
name tagn, which is a child of the descending chain from root, tag1, tag2,
through tag n-1, where the attribute attr1 of tag2 has the value 5.
