Problem with Greek characters

[cyb3rb0ss]

Hey everybody.

At the moment I am working on Harvester and especially in retrieving information from other repositories and the problem that I am facing with is the following:

When I have english characters everything works fine. No problem with repositories that have english characters.
On the other hand when I am trying to retrieve GREEK characters, the harvester stops suddenly.
For example if I have 250 records to receive form a repository and the problem appears on the 6th record, then stops at the 6th record and stops receiving the other 244 records.

My purpose is to fix that problem.
One idea would be somehow to find what (greek) characters are causing the problem and try to solve the problem by fixing or replace them so the procedure will proceed normally without stopping.

Could you please inform me and help me in which folders and *.php files have I to look in order to find a solution?
It is a very important prob that I have to solve.

Thank you.

Hi cyb3rb0ss,

The first thing to establish is whether or not your data source is serving up invalid XML. Are you familiar with OAI requests? If so, I'd suggest fetching a few manually and checking their validity using an XML validator such as xmllint.

I am newbie in the subject.
What does the XML Validator specifically? Is it checking something?

Hi cyb3rb0ss,

An XML validator will check to see that the XML document that the harvester is collecting from your data source is valid, i.e. that it doesn't contain any mismatched XML tags or invalid characters that would prevent it from parsing and loading the content. If there is invalid content, you'd be best off correcting it in your data source rather than trying to work around it with the harvester.
