i have a very strange problem which i cannot solve at the moment.
i try to parse a xml string with Regex.Matches to get all xml Nodes with a specific name.
it worked until now.
i have a xml input string with exactly 30 xml nodes named “row”
for some freaky reason my code returns me 26 nodes..
i have actually NO idea why there are 4 missing.
Heres my code to parse the data:
public static List<String> getXMLNodeContentFromSQLQueryString(String queryString, String rowName)
{
List<String> returnVal = new List<string>();
MatchCollection matchCollection = Regex.Matches(queryString, "<" + rowName + ">.*?</" + rowName + ">");
foreach (Match match in matchCollection)
{
String splitted = match.ToString();
splitted = splitted.Replace("<" + rowName + ">", "").Replace("</" + rowName + ">", "");
returnVal.Add(splitted);
}
if (returnVal.Count == 0)
returnVal.Add("");
return returnVal;
}
heres the xml string

and ideas?
thanks
SOLVED!!!!!!!!!!!!!!!
Still have no idea where the problem was but solved the problem with using XMLReader thanks for you advices heres the code for interested people.
public static List getXMLNodeContentFromSQLQueryString(String queryString, String rowName)
{
List returnVal = new List();
// load contents of file
TextReader textReader = new StringReader(queryString);
// process file contents
XmlDocument domDoc = new XmlDocument();
domDoc.Load(textReader);
XmlNodeList nodeList = domDoc.GetElementsByTagName(rowName);
foreach (XmlNode node in nodeList)
{
returnVal.Add(node.InnerXml);
}
return returnVal;
}
In each of the non returned rows (the Rows with OperationIDs of 18, 21, 24, and 25), there is one or more “\r\n” in the text, which causes the Regex to not match. Getting rid of them, or replacing them temporarily will return all 30 rows.
However, using an XML parser as you now have is definitely the right way to go.
