Question 1

What is XSLT and its primary purpose?

Accepted Answer

XSLT (Extensible Stylesheet Language Transformations) is a language used for transforming XML documents into other formats such as HTML, XML, or plain text. Its primary purpose is to apply transformations and style elements to XML documents, making them more suitable for presentation and data exchange between systems.

Question 2

What are the essential components of an XSLT stylesheet?

Accepted Answer

The essential components of an XSLT stylesheet include:
1. XML declaration and XSLT namespace: Every XSLT document must have an XML declaration at the beginning and an XSLT namespace.
2. Template rules: These are the set of instructions that tells the processor how to transform the input XML document.
3. XPath expressions: These are used to navigate and select specific parts of the XML document.
4. Output method: Specifies the output format, such as HTML, XML, or plain text.

Question 3

What is an XSLT processor and its role in XSLT transformations?

Accepted Answer

An XSLT processor is a software tool or library that reads and interprets an XSLT stylesheet, accepts an input XML document, and generates a transformed output document according to the rules specified in the stylesheet. The processor is responsible for applying the stylesheet to the input XML document and generating a transformed output document as specified by the XSLT rules.

Question 4

What are the differences between XSLT and XPath?

Accepted Answer

XSLT is a language used for transforming XML documents into other formats, while XPath is a language used for navigating and selecting nodes in XML documents. XSLT mainly focuses on applying styles and transformations to XML documents, whereas XPath focuses on querying information within XML documents. Although XSLT uses XPath expressions to select elements and attributes for transformation, they serve separate purposes and are distinct languages.
