Hi all,
could someone please help me to find a way to script the creation of new
wiki pages from data/text saved in html files?
I’m trying to (semi)automatically organize and upload data to new wiki
pages, i.e. analyze and plot data with an external program, sve the
information (including page name, etc.) in a html file, and then have some
sort of script take the html file – or objects from it – and create a wiki
page. It doesn’t have to be fully automatic and include a scheduled service
or similar, a script that I can run every day would be fine.
I did look for hints but I guess I’m too much of a beginner to piece
everything together. I found
http://extensions.xwiki.org/xwiki/bin/view/Extension/Create+Page+With+Object
which tells me that I can script a page creation.
Now my naïve question is: Where do I script this? I am not familiar with
Velocity (Python is my only scripting language), but willing to learn. From
what I could see in tutorials like
http://platform.xwiki.org/xwiki/bin/view/DevGuide/XWikiVelocityTraining I
put the velocity text in a wiki page (as opposed to run it in a terminal or
via some application outside of the wiki pages?
Does that mean I create a ‘control’ page with a script that’ll grab data and
creates new pages? I f so, it would be great if someone can point me to an
example.
Thank you
Sebastian

Correct. And you can invoke that from a command-line or cron
world if
you want with a curl (and some hard-coded passwords).
I f so, it would be great if someone can point me to

Using groovy is a good idea. It's a tick less limited than using
Velocity.
file = new java.io.File("filename.txt");
name = "Space." + file.getName();
doc = xwiki.getDocument(name);
println("Saving to document [[${doc}]].")
doc.setContent(org.apache.commons.io.FileUtils.readFileToString(file,
"utf-8"));
doc.setTitle("My beautiful page");
doc.setSyntaxId("xhtml/1.0");
doc.save("Fetching from ${file.getPath()}.");
Hope it helps.

I`m not much of a Python fan, but if you say you`re into it, you could
always try the
http://extensions.xwiki.org/xwiki/bin/view/Extension/Python+Macro and
script your way using your favorite language :)
If you try it, let me know how it went ;)
For scripting API see http://platform.xwiki.org/xwiki/bin/view/DevGuide/API
and the available bindings at
http://extensions.xwiki.org/xwiki/bin/view/Extension/Script+Macro
Now, for your particular use case, you could either create a new wiki page
and:
1) use the HTML syntax directly for that wiki page and just dump your HTML
content in it or
2) use the rendering script service ($services.rendering, i.e.
https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwi…)
to parse the HTML content into XDOM and then render it to xwiki/2.1 syntax
that you can then save inside the newly created page
Depends where you want to go with it.
Hope this helps,
Eduard

Thank you both, this helped me a lot.
I think right now I'm mostly battling the linked images in the original html files.
Xwiki uses relative paths and those are not valid anymore after converting to a wiki page.
I think I need to handle this when I create the html files and embed the images as text -
ugly but the only option I see right now.
Cheers
Sebastian

Here would be a continuation, before the document.save of course.
The imports should be put first.

import java.util.regexp.*;
import org.apache.commons.io.FileUtils;

import com.xpn.xwiki.api.*;
java.util.regexp.Pattern pattern = Pattern.compile("<img

Matcher m = pattern.matcher(html);
println("<ul>")
while(m.find()) {
URL u = new URL(pageURL, m.group(1));
String imageName = u.getPath().replaceAll(".*/","");
println("<li><a href='${u}'>${imageName

File tmp = new File("/tmp/xxx.png");
FileUtils.copyURLToFile(u, tmp);
// now fetch and store
byte[] content = FileUtils.readFileToByteArray(tmp);
//println("Attachment is of size ${content.length} and is named
${name}");
Attachment attachment = doc.addAttachment(imageName , content);
println(" has become <a href='${doc.getAttachmentURL(imageName

}
println("</ul>");
