我有一個C#程序循環瀏覽表單庫中的所有表單(啓用瀏覽器),並將XML節點注入每個表單(對於新提升的字段) 。出於某種原因,當XML保存回表單時,前幾個標籤被剝離。具體而言,這些標籤是:InfoPath表單XML的程序化更新剝離標籤
<?xml version="1.0"?>
<?mso-infoPathSolution name="urn:schemas-microsoft-com:office:infopath:Contractor-DB-Form:-myXSD-2009-09-10T18-19-55" solutionVersion="1.0.1.1100" productVersion="12.0.0.0" PIVersion="1.0.0.0" href="http://echouat.rbs.us/npe/FormServerTemplates/Contractor_DB_Form.xsn"?>
<?mso-application progid="InfoPath.Document" versionProgid="InfoPath.Document.2"?>
<?mso-infoPath-file-attachment-present?>"
我的代碼來更新XML如下:
private static SPListItem InsertXmlNode(SPListItem infoPathForm, string nodeToUpdateStr, string nodeToInsertStr,
string nodeInnerXmlStr, string firstNode)
{
//load form into xml document
byte[] fileBytes = infoPathForm.File.OpenBinary();
MemoryStream itemStream = new MemoryStream(fileBytes);
//Stream itemStream = infoPathForm.File.OpenBinary();
XmlDocument xmlDoc = new XmlDocument();
XmlNamespaceManager xmlNameSpaceMgr = new XmlNamespaceManager(xmlDoc.NameTable);
xmlNameSpaceMgr.AddNamespace("my", "http://schemas.microsoft.com/office/infopath/2003/myXSD/2009-09-10T18:19:55");
xmlDoc.Load(itemStream);
itemStream.Close();
//inject xml
XmlNode nodeToUpdate = xmlDoc.SelectSingleNode(firstNode + nodeToUpdateStr, xmlNameSpaceMgr);
//only insert if doesn't already exist
if (xmlDoc.SelectSingleNode(firstNode + nodeToUpdateStr + "/" + nodeToInsertStr, xmlNameSpaceMgr) == null)
{
updateCounter++;
XmlNode nodeToInsert = xmlDoc.CreateNode(XmlNodeType.Element, nodeToInsertStr, "http://schemas.microsoft.com/office/infopath/2003/myXSD/2009-09-10T18:19:55");
nodeToInsert.InnerText = nodeInnerXmlStr;
nodeToUpdate.AppendChild(nodeToInsert);
//get binary data for updated xml
byte[] newXmlData = Encoding.UTF8.GetBytes(xmlDoc.DocumentElement.OuterXml);
MemoryStream newMemStream = new MemoryStream(newXmlData);
//write updated binary data to the form
infoPathForm.File.SaveBinary(newMemStream);
newMemStream.Close();
infoPathForm.File.Update();
}
return infoPathForm;
}
添加新節點的正常工作;我可以看到新的XML格式正確。只是將文件從MemoryStream加載到XmlDocument對象後,標籤纔會被剝離。一旦這些標籤丟失,這些表單將不再在IP中打開。
請幫助!
謝謝!
