    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…

    Scraping HTML using XPath is far nicer than through low-level text processing. But how to proceed, if your XPath tool cannot deal with the HTML, because it is not XHTML conform resp. properly formatted XML? My XPath tool is XMLStarlet: And it can also help reformatting HTML, so that XPath expressions can get applied. I…

    sadly enough even now in 2016 a lot of web pages are not XHTML conform, but getting them fairly conform is not that expensive: use “xmlstarlet fo –html –recover“ get the (cron or) Jenkins job to save the current page content in the job’s workspace let the Jenkins job compare the current to the last…

    https://wiki.jenkins-ci.org/display/JENKINS/Authenticating+scripted+clients To make scripted clients (such as wget) invoke operations that require authorization (such as scheduling a build), use HTTP BASIC authentication to specify the user name and the API token. This is often more convenient than emulating the form-based authentication. The article quote above mentions “buildToken“, but I don’t need it at all. The…

    I had done some XPath using XMLStarlet in a shell script, and I quite like it. Feeling “safe enough” with XPath I managed to deal with the Python XPath pitfall(s), and I quite like my 1st respective XPath Python script. And of course my Python script has a nicer CLI interface than my shell script.…

    Updating did not work at all. I needed a fresh installation from finkproject.org . And then: $ fink install coreutils xmlstarlet pwgen $ fink install xpdf … Nota bene: you should always upgrade fink before upgrading OS X.
