[opencms-dev] Remove nodes from a structured XML file

[Brabenetz, Harald]

Hi,

I have created a Helper Class:

Sources and Jar can be downloaded from (last SNAPSHOT from 6. April):

Example Usage:
---------------------------------------
getCmsObject().lockResource("/testXmlContent.html");
CmsFile file = getCmsObject().readFile("/testXmlContent.html");

XmlContentEditorHelper helper = new XmlContentEditorHelper(
    getCmsObject(), file, Locale.ENGLISH);
helper.setValue("Description", "New Description");
helper.removeValue("Title");
helper.removeAllValues("LinkList");
helper.writeContent();

getCmsObject().unlockResource("/testXmlContent.html");
---------------------------------------

regards,
Harald

Hi Peter

Our situation is more or less the same as yours - we have a number of news
articles, often several in one day, and we want to show the N latest
articles on the front page. 

This is the way we've implemented this: 
- each news article is one file (of type "structured content"). 
- each news article is placed in its permanent location, e.g.
/en/news/2010/02/newsarticle-from-february.html
- on the front page, we list the N latest articles in the sub-tree of
/en/news/

Since we're placing the articles in their permanent location from the very
start, search engines will index the content correctly upon the first crawl,
and we won't create broken links since we don't move the content around.

Not exactly the reply you were looking for perhaps, but I hope it helps you
in some way.

...and if you still want to do it the way you're suggesting, have a look
here, maybe it will give you an idea: http://tinyurl.com/yk74hy5

Best regards,
Paul
