OpenHAB: 2.5 Raspbian: 9 Does anyone have any ideas as to how I could parse the XML from this web page? It seems that it only displays the XML after being viewed by a browser. If I use a sendHttpGetRequest(URL) in a rule, it does not get the page properly. If I could just get the XML data from …

After some further work on this issue since last week, I have found a way to get the NWS XML data using an OpenHAB rule without having to bring it in from an external Powershell script (although I have that working, as well). Here are the basic commands that allow me to capture, parse the XML data …

I searched the forum and found this. Will it work for you? [image] NOAA Weather alerts using RSS feed (US only) Tutorials & Examples We had been scraping weather alerts from wunderground until they changed their API. This is a really simple solution that I fin…

I had looked at the alerts before. The problem I am running into with the NWS API which provides JSON-LD and XML formatted weather observations is that they are delayed (significant delays regularly) and often have null values. However, this page (which is adjustable to specific weather stations) …

Since you mentioned XML, would this work? [image] XPath - Transformation Services Transforms an XML input using an XPath(https://www.w3.org/TR/xpath/#section-Expressions) expression.

Thank you. The problem, however, is not with XPath. I need a way to programmatically gain access to the XML as displayed when the web page is opened in a web browser. That is the core issue. If there is a tool that will allow access to the XML and can also parse the data automatically, that woul…

Perhaps using Jython which is basically Python 2?

Again, the issue is not really one of parsing the data. The issue is finding some way to programmatically obtain the XML data automatically so that it can be parsed using one of the tools available.

I do not agree with your argument about the API being delayed, but if that is what you want, you can pull the data using executeCommandLine and curl. Just be aware that https://www.wrh.noaa.gov/mesowest/ gives… [image]

Are you using the old API? NOAA has two APIs, a new one and an old one. I did some messing around with NOAA awhile back which might be able to get you started. See [image] Which weather binding to use Bindings There are two APIs, an old one and a newer one. I …

I got the current NWS API working just fine in an OpenHAB rule that updates several weather items and have been watching it on a regular basis this week. That is how I know there are delays; plus, it regularly provides null values, and this happens from the two main NWS stations at the two airports…

[image] richard.w: I would just like to know if there is a way that someone could tell me how to regularly pull the XML from the URL I provided in the first post. Perhaps set up a bounty on bounty-source to attract help?
