31 sorting xml data with xslt

sorting xml data using xslt (extensible stylesheet language transformations) is a powerful way to manipulate and present xml data. xslt provides a straightforward way to transform xml documents into other formats, including sorted xml.

overview of the tutorial

this tutorial will cover:

1. basic understanding of xml and xslt.
2. sorting xml data using `xsl:sort`.
3. example xml data.
4. example xslt to sort the xml data.
5. explanation of the code.

1. basic understanding of xml and xslt

**xml (extensible markup language)** is a markup language used to store and transport data. it is both human-readable and machine-readable.

**xslt** is a language for transforming xml documents into other formats (like html, plain text, or even other xml). it allows for the manipulation of the structure and content of xml.

2. sorting xml data with `xsl:sort`

the `xsl:sort` element within an `xsl:apply-templates` or `xsl:for-each` construct allows you to sort the nodes being processed. you can sort based on specific child elements or attributes of the nodes.

5. explanation of the code

- **version and namespace declaration**: the first line declares the version of the xml and the xslt namespace.

- **output method**: the `xsl:output` element specifies that the output should be xml and should be indented for readability.

- **template matching on `/library`**: the first `xsl:template` matches the root element `library`. it creates a new root element `sortedlibrary` in the output.

- **applying templates with sorting**: inside the `sortedlibrary` element, `xsl:apply-templates` is used to process each `book` element. the `xsl:sort` element is used to sort the books by the `year ...
