Summary: C# XML parsing code with RegEx fails running on NAnt 0.86.29
Initial Comment:
C# XML parsing code with RegEx fails running on NAnt 0.86.2962.0
I installed the NAnt 0.86 (Build 0.86.2962.0; nightly; 10.02.2008) because bug
1859708 was fixed there. After that following C# code crashes while runs OK on
NAnt-0.85 and NAnt-0.86-beta1.
<property name="BuildNumber" value="2.0.0.0" />
<property name="BuildDate"
value="${string::substring(datetime::to-string(datetime::now()), 0,
2)}-${string::substring(datetime::to-string(datetime::now()), 3,
2)}-${string::substring(datetime::to-string(datetime::now()), 6, 4)}"/>
<property name="filepath" value="c:\projects\GlobalAssemblyInfo.cs"/>
<property name="filevss" value="${vssprojects}/GlobalAssemblyInfo.cs"/>
<script language="C#">
<imports>
<import namespace="System.Xml"></import>
<import namespace="System.Xml.XPath"></import>
</imports>
<code><![CDATA[
public static void ScriptMain(Project project)
{
string fileVersion = Path.Combine(project.BaseDirectory,
project.Properties["filepath"]);
StreamReader reader = new StreamReader(project.Properties["filepath"]);
string contents = reader.ReadToEnd();
reader.Close();
string replacement = string.Format(
"[assembly: AssemblyVersion(\"{0}\")]",
project.Properties["BuildNumber"]);
string replacement2 = string.Format(
"[assembly: AssemblyFileVersion(\"{0}\")]",
project.Properties["BuildNumber"]);
string replacement3 = string.Format(
"[assembly: AssemblyInformationalVersion(\"{0}\")]",
project.Properties["BuildDate"]);
string newText = Regex.Replace(contents, @"\[assembly\s*:
AssemblyVersion\("".*""\)\]", replacement);
string newText2 = Regex.Replace(newText, @"\[assembly\s*:
AssemblyFileVersion\("".*""\)\]", replacement2);
string newText3 = Regex.Replace(newText2, @"\[assembly\s*:
AssemblyInformationalVersion\("".*""\)\]", replacement3);
StreamWriter writer = new StreamWriter(fileVersion, false);
writer.Write(newText3);
writer.Close();
}
]]>
</code>
</script>
The code execution fails with the same errors on both machines with .Net SDK
and without it. Errors are as follows:
error CS0234: The type or namespace name 'Xml' does not exist in the namespace
'System' (are you missing an assembly reference?)
If <imports> … </imports> is omitted, nAnt returns following error (builds ok
on previous nAnt releases):
error CS0103: The name 'Regex' does not exist in the current context
Thanks for grate product, but please fix this issue or specify a workaround.

Thank you. However it takes even more than that -
System.Text.RegularExpressions needs to be referenced, and it is in
System.dll - not in mscorlib.dll as I thought. The final working code looks
like this:
<script language="C#">
<references>
<include name="System.dll" />
<include name="System.Xml.dll" />
</references>
<imports>
<import namespace="System.Text.RegularExpressions" />
<import namespace="System.Xml" />
<import namespace="System.Xml.XPath" />
</imports>
...
</script>
Thanks for your time and assistance. Too bad that writing c# sripts for
nAnt will be even harder now for beginners :(
Regards.

Michael,
You also need to import the System.Text.RegularExpressions namespace:
<script language="C#">
<references>
<include name="System.Xml.dll" />
</references>
<imports>
<import namespace="System.Text.RegularExpressions" />
<import namespace="System.Xml" />
<import namespace="System.Xml.XPath" />
</imports>
...
</script>
That info is also in the release notes.

Thanks for your comments but it does not resolve the issue - instead I get
this error:
error CS0103: The name 'Regex' does not exist in the current context
I tried it on environments with .Net 2.0 SDK installed and without it,
referencing dll from GAC or on file system, but with the same result:
<references> <include name="System.Xml.dll" /> </references>
or
<references>
<include
name="c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.XML.dll" />
</references>
However the script runs OK on NAnt-0.86-beta1 regardels do I specify
reference and import and how (GAC or file system).
Thanks for your time.

Michael,
You need to add a reference to the System.Xml assembly:
<script language="C#">
<references>
<include name="System.Xml.dll" />
</references>
<imports>
<import namespace="System.Xml"></import>
<import namespace="System.Xml.XPath"></import>
</imports>
...
</script>
This breaking change is documented in the release notes:
http://nant.sourceforge.net/nightly/latest/releasenotes.html
Depending on the feedback that I get for this change, I might still revert
it before the final release of NAnt 0.86.
