Eclipse XPath evaluation plugin

The plugin works well with well-formed XML but fell in a heap with HTML and XHTML documents. Would be great if this plugin could be more general purpose and able to ignore small semantic issues with less well-formed markup.

Hi,

I tried to install this tool, but I get an error like this:

Unknown Host: http s:// r a w. gith ubus erco ntent.com/s toupa 91/ eclipse-xpa th-evalu ation-p lugin/ma ter/ecli pse-xpath -eval uati on-pl ugin-u pdate -site/co nten t.x ml

r aw.g ithubuse rcon tent.c om

Because Eclipse "Sorry, we do not allow comments to contain external links [URL]. Feel free to edit your post."

I added some" " in the link.

does anyone know the solution to this?

Thanks a lot

Andreas

I'm learning XPath and looked for an interpreter and this one gave me a first contact with it but apparently it has issues and interpreting XPath functions. Retyping the queries from the video I cannot get a result and in the video it appears well.

Now I've looked at the syntax of the concat function and I don't understand what's going on. Either it states that I can't use a single argument, Either it states that I am restricted on the first one, either it returns only the number of result but does not display the data.

So it seems it is buggy.
You can reproduce what I'm saying by downloading this XML file and trying that query for instance.
Look for Institute for Informatics Georg-August-Universität Göttingen mondial database. They provide an XML file

and the queries:

/mondial/country[population < 10000]/name/concat('Population: ', name)  <- returns no value
concat(/mondial/country[population < 10000]/name,' test ') <- Returns msg "A sequence of more than 1 item is not allowed as the first argument of concat()"
a working query from the video was

/mondial/country[population > 300000000]/name/concat(name,' -> ', population) <- Just returns the number of elements in the resultset but do not display the data.

I checked this URL in a browser and it is in fact bad - returns 400 Bad Request

For those who have been using previous versions of this plugin, please uninstall it and install it again either through Eclipse Marketplace or use this new update site:

https://raw.github.com/stoupa91/eclipse-xpath-evaluation-plugin/master/eclipse-xpath-evaluation-plugin-update-site/

The reason for this is, that the plugin (and its update site) has been moved from Google to Github and it wouldn't get updated to this latest or future releases.

Hi,

I get always an exception when running the namespace loader.
Here are the details:
An internal error occurred during: "Namespace loader".
XPathFactory#newInstance() failed to create an XPathFactory for the default object model: hattp://java.sun.com/jaxp/xpath/dom with the XPathFactoryConfigurationException: javax.xml.xpath.XPathFactoryConfigurationException: java.util.ServiceConfigurationError: javax.xml.xpath.XPathFactory: bundleresource://853.fwk1407675409/META-INF/services/javax.xml.xpath.XPathFactory:2: Illegal configuration-file syntax

Any hints for solving the problem?

Kind regards

When a file has a default namespace (xmlns="something") without prefix nothing is selectable.

Even when adding manualy the namespace value association with an empty string.

I have to define a prefix and use that prefix all arround...

- does not gather namespace info from the file itself, would be very easy to implement; it's quite tedious to fill it in by hand, esp. taking into account that this info is forgotten when you close the xml file
- would be nice to have options to ignore namespaces, etc.

A list of the returned XPath objects would in some cases be preferable, the raw xml is a lot of clutter if you are looking for all results of a complex query. A simple 'Number of results' in a Text widget would already be a big improvement.
In total: very nice plugin, also without the above request. Great that the namespaces work like they should (a feature that many online XPath evaluators miss or don't implement right).
Drag&Drop from the browser into Indigo also worked fine for me, chiq.

Kind regards, tw

Looks good, I also installed it via Drag&Drop from the browser successfully into Indigo. Why haven't you converted the Google Code Project into EclipseLabs btw., or started there in the first place?
