I use command line validators but Oxygen is great for thorough debugging, so we will use Oxygen.

All descendants. **`select="following-sibling::\_"`** -- all nodes after that node gt for greater than and lt for lesser than when testing logic statements. Can't use < or > because that is used in the XML structure. Three conditional statements: if, choose, for each. --- # Examples * Example: Roles * Example 2: [PBCore to DublinCore](https://github.com/ablwr/MIRCDVRXSLT/blob/master/pbcore_to_dc.xsl) * Example 3: [MediaConch](https://mediaarea.net/MediaConch) output to HTML, to TXT, to XML * Example 4: MARC to MODS in NYPL Metadata Management System * Example 5: MODS to NYPL Digital Collections * Example 6: [LoC MARC to MODS XSL](http://www.loc.gov/standards/mods/v3/MARC21slim2MODS3-3.xsl) --- # Workshoppin' * scripts/mediainfo [xml](/scripts/mediainfo.xml) [xsl](/scripts/mediainfo_simple.xsl) * scripts/roles [xml](/scripts/roles.xml) [xsl](/scripts/roles.xsl) * scripts/movies [xml](/scripts/movies.xml) [xsl](/scripts/movies.xsl) | [answers](/scripts/movies_answer.xsl) * scripts/movies (html) [xsl](/scripts/movies_html.xsl) | [answers](/scripts/movies_html_answer.xsl) --- # When in doubt... .center[] --- # Additional Resources ### Resources - [XSLT & XPath Cheatsheet](http://scraping.pro/res/xpath-cheat/XSLT-1.pdf) - [XPath/CSS/DOM/Selenium Rosetta Stone](http://scraping.pro/res/xpath-cheat/xpath_css_dom_recipes.pdf) - [XSL functions](http://www.w3schools.com/xsl/xsl_functions.asp) - [Stanford Online: XSLT Mini-course](https://lagunita.stanford.edu/courses/DB/XSLT/SelfPaced/about) - [Transorming XML with XSL](http://programminghistorian.org/lessons/transforming-xml-with-xsl) ## Command line tools - [xsltproc](http://xmlsoft.org/XSLT/xsltproc2.html) (Macs) - [ffmpeg](https://ffmpeg.org/) --- # Learning more - [Computers](/presentations/computers.html) - [Metadata](/presentations/metadata.html) - [Data wrangling](/presentations/data-wrangling.html) - [XML](/presentations/xml.html) [Home](/)
