Problem with parsing double value from xml file

[Martin Pöpping]

Hello,

I´ve a problem with parsing a double value from an xml file.

My code looks like this:

int concept_id;
double rank;
XmlElement root = documentXMLStri ng.DocumentElem ent;
XmlNodeList records = root.ChildNodes ;
XmlAttributeCol lection attributes;

for (int i = 0; i < records.Count; i++)
{
attributes = records.Item(i) .Attributes;
concept_id=int. Parse(attribute s.GetNamedItem( "id").InnerText );
rank=double.Par se(attributes.G etNamedItem("ra nk").InnerText) ;

concepts_.Add(c oncept_id, rank);
}
The variable concepts_ is a Hashtable.

A typical XML file looks like this:

<root>
<concept id="20114" rank="1" />
<concept id="13786" rank="0.5" />
</root>

The problem is with parsing the double value:
rank=double.Par se(attributes.G etNamedItem("ra nk").InnerText) ;

For example with:
<concept id="13786" rank="0.5" />
the rank is parsed as "5.0" instead of "0.5"
Do you have any idea what happens?
Regards,

Martin

Hi,

What are your current regional settings, specifically the decimal and
thousands separator?

When working with XML I would suggest that you use the XmlConvert.ToDo uble,
this
will parse the content in accordance with the XSD spec for data types rather
than the current
locale settings.

Hope this helps
