  • xmlstarlet: how to deal with a default namespace in XPath expressions?

    I ran into this problem, when I tried to extract values from JasperReport’s JRXML using xmlstarlet. JRXML files introduce a default namespace (which does not seem to serve a lot), and XPath processors need to take that into account. When I searched for help in xmlstarlet’s documentation and on the web, I came across this…

    All these packages resp. utilities do not require Windows admin rights for getting them “installed” – actually they do not need “a Windows system installation”. Below C:\Users\jhayek I created a couple of subdirectories: opt: every package resp. utility has its own subdirectory below there bin: some .bat and .sh (BusyBox ash) scripts go there Packages resp. utilities:…

    https://codex.wordpress.org/WordPress_Feeds https://codex.wordpress.org/WordPress_Feeds#Finding_Your_Feed_URL 1st approach: xmlstarlet with an XPath expression (rss/channel/item/link) + shell wrapper. 2nd approach: XQuery script looping over rss/channel/item (+ shell wrapper). I am glad to upload it to my github area, in case somebody is interested. Update 2016-08-26: By default WordPress creates an RSS feed with just 10 entries. I don’t create my diary entries…

    “In production” I have been using a Bash+xmlstarlet script, that I wanted to optimise by rewriting it into an XQuery script. This would be my 1st XQuery script after a couple of months of exercising XQuery through Priscilla Walmsley’s book and Saxon9HE – a couple of hours per week only because of my entire workload. During…

    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…

    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…
