I’m trying to transform one XML format to another using XSL. Try as I might, I can’t seem to get a result.
I’ve hacked away at this for a while now and I’ve had no success. I’m not even getting any exceptions. I’m going to post the entire code and hopefully someone can help me work out what I’ve done wrong.
I’m aware there are likely to be problems in the xsl I have in terms of selects and matches, but I’m not fussed about that at the moment.
The output I’m getting is the input XML without any XML tags. The transformation is simply not occurring.
Here’s my XML Document:
<?xml version="1.0"?>
<Transactions>
<Account>
<PersonalAccount>
<AccountNumber>066645621</AccountNumber>
<AccountName>A Smith</AccountName>
<CurrentBalance>-200125.96</CurrentBalance>
<AvailableBalance>0</AvailableBalance>
<AccountType>LOAN</AccountType>
</PersonalAccount>
</Account>
<StartDate>2010-03-01T00:00:00</StartDate>
<EndDate>2010-03-23T00:00:00</EndDate>
<Items>
<Transaction>
<ErrorNumber>-1</ErrorNumber>
<Amount>12000</Amount>
<Reference>Transaction 1</Reference>
<CreatedDate>0001-01-01T00:00:00</CreatedDate>
<EffectiveDate>2010-03-15T00:00:00</EffectiveDate>
<IsCredit>true</IsCredit>
<Balance>-324000</Balance>
</Transaction>
<Transaction>
<ErrorNumber>-1</ErrorNumber>
<Amount>11000</Amount>
<Reference>Transaction 2</Reference>
<CreatedDate>0001-01-01T00:00:00</CreatedDate>
<EffectiveDate>2010-03-14T00:00:00</EffectiveDate>
<IsCredit>true</IsCredit>
<Balance>-324000</Balance>
</Transaction>
</Items>
</Transactions>
Here’s my XSLT:

Here’s my method to transform my XML:
public string TransformToXml(XmlElement xmlElement, Dictionary<string, object> parameters)
{
string strReturn = "";
// Load the XSLT Document
XslCompiledTransform xslt = new XslCompiledTransform();
xslt.Load(xsltFileName);
// arguments
XsltArgumentList args = new XsltArgumentList();
if (parameters != null && parameters.Count > 0)
{
foreach (string key in parameters.Keys)
{
args.AddParam(key, "", parameters[key]);
}
}
//Create a memory stream to write to
Stream objStream = new MemoryStream();
// Apply the transform
xslt.Transform(xmlElement, args, objStream);
objStream.Seek(0, SeekOrigin.Begin);
// Read the contents of the stream
StreamReader objSR = new StreamReader(objStream);
strReturn = objSR.ReadToEnd();
return strReturn;
}
The contents of strReturn is an XML tag (<?xml version="1.0" encoding="utf-8"?>) followed by a raw dump of the contents of the original XML document, stripped of XML tags.
What am I doing wrong here?
I have verified that the provided transformation when applied with XslCompiledTransform on the provided XML document produces very meaningful (probably the desired) output.
Let me guess: maybe the provided XML is not the same as the one used in practice? Maybe you have a default namespace?
If so, you need to match nodes in the default namespace — not in “no namespace”.
You can easily verify if the XmlElement that you provide is in a namespace: inspect/print its
NamespaceURIproperty.
