This example demonstrates how XPath and the XQuery `typeswitch` expression can be used to selectively process different node types in an XML document. It shows a TEI-encoded text where comments, text nodes, and `<p>` elements are handled distinctly, with element attributes joined into a space-separated string. The code relies on the XQuery 3.0 standard library functions `fn:string` and `fn:string-join`, operating on the TEI namespace declared in the document. The visualization is static, with no graphical rendering; instead, it highlights the programmatic traversal and conditional branching over the XML tree structure.

<title>Testing XPath

This example demonstrates how an XML TEI document’s structure can be queried using XPath and represented as an interactive node-link diagram. It displays the document’s hierarchical elements—such as `teiHeader`, `text`, `body`, and `p`—as circles connected by links, with text content visible alongside node labels. The visualization uses D3.js’s `d3.hierarchy` and `d3.tree` layout to calculate positions, while `d3.zoom` enables panning and zooming. The code loads the XML via a local file and parses it with `DOMParser`, then applies XPath expressions via `document.evaluate` to extract elements and text for rendering.

This example of recursive descent in XQuery is adapted from Joe Wicentowski (https://gist.github.com/joewiz/2331558#file-typeswitch-skeleton-xq). It rather naively formats scenes from the Folger Library Shakespeare TEI editions for display in HTML. This example is intended for the demonstration of the concept, not actual use.

This example shows recursive descent in XQuery rendering scenes from a Folger Library Shakespeare TEI edition into HTML. It demonstrates how a typeswitch pattern matches distinct TEI elements—such as `tei:head`, `tei:w`, `tei:stage`, and `tei:speaker`—to produce formatted output like headings, stage directions, and speaker labels. The code relies on XQuery 3.0’s built-in `typeswitch` and function recursion, using `local:render` and `local:recurse` to traverse the XML tree. It serializes to XHTML via `exist:serialize`, pulling the source document from `/db/shakespeare/JC.xml` without external libraries.

XPath Examples - Mellon Institute

This example demonstrates how XPath queries navigate and extract specific content from a TEI-encoded document of the Mellon Institute at Vanderbilt. It shows the progression from simple absolute paths to descendant-or-self axes, then to predicate-based filtering, and finally to more complex relational paths. The code uses the XPath API to select titles, names, sex attributes, and speaker-related paragraphs, referencing the updated TEI Guidelines for the sex element. The example is presented as a gist authored by CliffordAnderson, with the source data being the structured XML markup of the institute’s records, illustrating query patterns for text extraction and attribute matching.

Practice XPath expressions for USC

This example demonstrates XPath expression practice through a visual interface, showing how distinct values and hierarchical navigation can be explored interactively. It uses the USC document structure to highlight element names and path syntax, including `self::element()` for text-bearing nodes and child-axis selectors like `/child::usc:uscDoc/child::usc:main`. The visualization is driven by a gist from CliffordAnderson, with the code relying on XQuery (implied via the `.xqy` file) to compute distinct names and parent-child relationships. The rendering approach is not explicitly shown, but the focus remains on illustrating XPath’s filtering and traversal capabilities against a sample XML document.

Here's the query we started in class today.

This example demonstrates how to extract the title and author from a TEI-encoded XML document stored in a database. It shows the direct retrieval of text content from nested XML elements, returning both pieces of metadata as a sequence. The code uses the XQuery language with the `fn:doc()` function to access the document and XPath expressions to navigate the TEI namespace. It specifically traverses the `teiHeader/fileDesc/titleStmt` structure to pull the title and author values, illustrating a fundamental pattern for querying structured text documents in an XML database environment.

{$title || " - "}

This example displays a list of EAD (Encoded Archival Description) titles sorted alphabetically from a collection of finalized XML files, rendered as plain paragraph elements in an XHTML page. It uses XQuery 3.1 with the `fn:collection` function to gather titles from `titleproper[@type="filing"]` nodes, and a local template function `local:template` constructs the HTML output, setting a dynamic heading level and tab title. The code demonstrates a server-side, XML-to-HTML transformation pipeline without client-side JavaScript libraries or interactive visualization components.

XQuery Full Text

This example demonstrates the evolution of text search in XQuery, from basic string matching to full-text querying with linguistic processing. It shows how `fn:contains` and `fn:matches` perform literal pattern matching, while the XQuery Full Text 3.1 features—`contains text`, `using stemming`, `ft:mark`, and the `score` clause—enable case-insensitive, stem-aware, ranked search results. The code queries a collection of TEI-encoded texts (`vwwp_tei`) and returns matched paragraphs, with scoring wrapped in XML output and string formatting via `format-number`.

For XQuery4Humanists

This example visualizes the frequency and distribution of words extracted from a TEI-encoded poem, processing the text to remove punctuation, normalize case, and tokenize it into a list. The visualization shows the resulting word list as a simple textual display, highlighting the raw output of the XQuery processing pipeline. The code uses XQuery 3.0 functions like `fn:tokenize`, `fn:lower-case`, and `fn:replace` to clean the data, pulling the source directly from a remote XML file hosted on GitHub. The rendering relies solely on the XQuery return, with no additional JavaScript or charting libraries involved.
