We are having trouble encoding special characters less than 32 (excluding 9, 10, and 13). One server is creating an XML DOM and returning the XML as a string. The calling server is then getting this XML string and loading it into a DOM. The following VB test app shows that assigning a special character to the Text property doesn't encode it in a way that a later call to loadXML will work:
Dim xmldoc As MSXML2.DOMDocument
Dim xmldoc2 As MSXML2.DOMDocument
Dim strXML As String
For x = 1 To 255
Set xmldoc = New MSXML2.DOMDocument
Set pi = xmldoc.createProcessingInstruction("xml", " version='1.0'")
xmldoc.appendChild pi
Set e = xmldoc.createElement("test")
e.Text = "chr(" & x & ")=" & Chr(x) & ";"
xmldoc.appendChild e
strXML = CStr(xmldoc.xml)
Set xmldoc2 = New MSXML2.DOMDocument
xmldoc2.loadXML strXML
If xmldoc2.parseError.errorCode <> 0 Then
Debug.Print x, "parseError:" & xmldoc2.parseError.reason
End If
Set xmldoc = Nothing
Set xmldoc2 = Nothing
Next
The output is:
1 parseError:An invalid character was found in text content.
2 parseError:An invalid character was found in text content.
3 parseError:An invalid character was found in text content.
4 parseError:An invalid character was found in text content.

24 parseError:An invalid character was found in text content.
25 parseError:An invalid character was found in text content.
26 parseError:An invalid character was found in text content.
27 parseError:An invalid character was found in text content.

29 parseError:An invalid character was found in text content.
30 parseError:An invalid character was found in text content.
31 parseError:An invalid character was found in text content.
I tried playing with the encoding on the initial DOM document, but it has no effect.
How do I properly encode these special characters?
