Espacenet have changed their URL format, simply replace the Detect code in Scaffold by the following :

function detectWeb(doc, url) {

if(doc.location.href.match("searchResults")) {
return "multiple";
} else if (doc.location.href.match("publicationDetails")) {
return "patent";
}
}

In addition, the title xpath have changed too, replace the older by :

/html/body/table[2]/tbody/tr[1]/td[3]/h2

Amacom73, what you need to do is:

1. Go into Z preferences (cogwheel menu in Z), and in the 'Advanced' tab, click on Data Directory;
2. Click on the 'storage' folder and locate the file called 'ESpacenet.js';
3. Open with a text editor like Notepad, or better Notepad Pro;
4. CLOSE Firefox;
5. Back in the test editor, replace the function detectWeb in accordance with tperki's second post above;
6. Replace the xpath statement for the title section in accordance with tperki's second post above (this is the line starting 'var xpath' under the line '//Get title');
7. Change the line that starts "lastUpdated" (near the top of the file) with the new date and time in the format YYYY-MM-DD hh:mm:00;
8. Save and close the file.
9. Re-start FF.

You may be able to use Scaffold as an alternative but this add-on doesn't seem to work with Zotero 1.5b2.1.

Thanks to tperki and cavallad,
I got the espacenet-translator working now.

But has somebody a solution for integration of an automatic full-text pdf-download in this espacenet translator. This would be very helpfull.

Thanks amacom73,

i tried to use the zotfile plugin, but I got it until now not working. This problem, I discuss further in an other discussion.

pdf's direct from espacenet: captcha could be really a problem.

Not yet-- if no one works on it in the meantime, post here again in a month or two. If I have a bit more time, I'll take a look.

That would be great. Direct them to http://www.zotero.org/support/dev/make_your_site_zotero_ready and the development mailing list zotero-dev (http://groups.google.com/group/zotero-dev/).

Further discussion of the translator specifics should be on the developer list, zotero-dev (http://groups.google.com/group/zotero-dev), but note that you should try to craft XPath expressions that are more flexible-- the ones you have look they were created automatically by Firebug or the like, and they are very fragile. Instead of //table[1]/tbody/tr[5]/td, use //table[@class="tableType3"]/tbody/tr[5]/td or //table[@class="tableType3"]/tbody/tr[contains(th/text(),"Applicant(s)")]/td. Navigating tables is messy, so enumeration is sometimes not avoidable, but enumeration outside of data tables is something to avoid; some of your expressions are fragile enough to be thrown off by the addition of a single DIV or TR anywhere in the page. If you have questions, send them to zotero-dev and we'll get this committed. Thanks for stepping up and making a great start at a translator!

Hi edoleroy,

thanks for your work. But for me the modified translator is not working. I got no "Zotero" Button in the address line of my firefox, which indicates that the espacenet-site is zotero-ready.

(firefox 4.0.1, zotero 2.1.6, windows xp sp2)

Note that the new translator is designed specifically for the version at worldwide.espacenet.com

Hi,
for me the translator do not work.

Here a sample url:
http://worldwide.espacenet.com/publicationDetails/biblio?DB=EPODOC&adjacent=true&locale=en_EP&FT=D&date=20071221&CC=KR&NR=20070120187A&KC=A

I get no zotero icon in the addressbar of the firefox.

Edouard - with "replace the code" you mean "replace the file Espacenet.js completely, or not.

Now the translator is working.
Many Thanks Ajlyon.

Unfortunately, the Espacenet translator seems to be broken again. The .js file from ajlyon is no longer available on github so I cannot try that path anymore.
Could anyone provide assistance fixing the problem with the translator? This was such a great feature.

TIA.

Espacenet should now work.
