    I found this function, but it pads on the right: http://www.xqueryfunctions.com/xq/functx_pad-string-to-length.html : functx:pad-string-to-length I derived pad-string-to-length-on-the-left from it: https://github.com/JochenHayek/misc/blob/master/xqueryfunctions/pad-string-to-length-on-the-left.xqy https://github.com/JochenHayek/misc/blob/master/xqueryfunctions I use it around format-integer and format-number, e.g. let $net_amount_formatted := local:pad-string-to-length-on-the-left( format-number( data($invoice/@net_amount) , ‘#,###.#####’ ) , ‘ ‘ , 12 )

Looks like there is nothing in the “built-in library”. Looks like there is no functx:pad-integer-to-length as well, but functx:pad-string-to-length looks intriguing – but it only pads on the right. I created a variant, that pads on…

    http://xmlstar.sourceforge.net/doc/UG/xmlstarlet-ug.html#idm47077139665568 http://xmlstar.sourceforge.net/doc/UG/xmlstarlet-ug.html I really like “xmlstarlet elements …” – but these very nice and useful XPath expressions come without index. So what if you really, really need them with indexes? I am not sure, you can write a general utility, that rewrites these XPath expressions without index into XPath expressions with index, but for my…

  • extract your build steps from a Jenkins CI job to ordinary and “easy to edit” flat files

    Over time Jenkins jobs can grow into something “a little confusing”, in other words: like cancer. The Jenkins developers were thoughtful enough to provide an API to all the data structures, that Jenkins and its jobs operate on, so we are able to export an entire Jenkins job as XML. You certainly do not want…

    https://github.com/JochenHayek/misc – pls find my script here! First I wrote this as a Shell script … calling XMLStarlet resp. SaxonHE (for XPath) and curl (for retrieving the Jenkins details as XML files). $ …/jenkins_find_jobs.sh https://integration.wikimedia.org/ci folder … freeStyleProject … matrixProject … The listing is quite helpful for documentational purposes. I was really proud on my little achievement…

    http://www.gnu.org/software/qexo/XQ-Gen-XML.html – search there for “Generate all the HTML output files“! … by putting them in a single large XML object – then use a post-processor to split this into separate files. (Alright this isn’t really a true “single XQuery run” approach. But it is close enough.) With Saxon-HE there is no way to write to separate text…

    Xidel is a command line tool to download html/xml pages and extract data from them using CSS 3 selectors, XPath 3 expressions or pattern-matching templates. http://www.videlibri.de/xidel.html https://en.wikipedia.org/wiki/XQuery – I am “watching” the changes on this article, and somebody just added Xidel, that’s how I came across Xidel Cygwin’s and Fink’s repository do not have Xidel, but Xidel’s…
