Migrating Wiki Pages Remotely – Part 04
Note, this series starts at blogs.msdn.com/dwinter/archive/2008/06/28/migrating-wiki-pages-remotely-part-01.aspx
We just looked at using copy.asmx to get WikiField. Now let’s look at getting the field by using just lists.asmx. You may notice that the segment of code I took this from is using the destination web service instead of the source. This one is interesting because if WikiField is empty, you can see how I parsed the ows_MetaInfo propertybag.
if (txt_SelectedWiki2.Text.Length > 0)
{
Server2WS.Lists s2L = new WikiMigrator.Server2WS.Lists();
s2L.Url = txt_SiteName2.Text.Trim().TrimEnd("/".ToCharArray()) + "/_vti_bin/lists.asmx";
s2L.Credentials = System.Net.CredentialCache.DefaultCredentials;
try
{
// I know a lot of folks want to define their own view
// instead of using the stock ones. I threw this in as
// an example.
XmlDocument xmlDocLI = new System.Xml.XmlDocument();
XmlNode ndQueryLI = xmlDocLI.CreateNode(XmlNodeType.Element,"Query","");
XmlNode ndViewFieldsLI = xmlDocLI.CreateNode(XmlNodeType.Element,"ViewFields","");
XmlNode ndQueryOptionsLI = xmlDocLI.CreateNode(XmlNodeType.Element,"QueryOptions","");
// I’m not actually using ndQueryOptionsLI, it is
// here as an example
ndQueryOptionsLI.InnerXml = "<IncludeMandatoryColumns>FALSE</IncludeMandatoryColumns>" +
"<DateInUtc>TRUE</DateInUtc>";
ndViewFieldsLI.InnerXml = "<FieldRef Name='FileRef' />" +
"<FieldRef Name='WikiField' />" +
"<FieldRef Name='LinkFilename' />";
// I’m not actually using ndQueryLI, it is here as an example
ndQueryLI.InnerXml = "<Where><Eq><FieldRef Name='FileRef' />" +
"<Value Type='Text'>[server-relative URL of wiki page]</Value></Eq></Where>";
//
// Need to provide a large number or we will restrict at the default 100 items if null
XmlNode ndListItems = s2L.GetListItems(txt_SelectedWiki2.Text, null, null, ndViewFieldsLI, txtNumberRows.Text, null, null);
XmlNode ndListItemDetail = ndListItems.ChildNodes[1];
foreach (XmlNode item in ndListItemDetail.ChildNodes)
{
try
{
if (item.Attributes != null)
{
string itemName = item.Attributes["ows_LinkFilename"].Value;
Trace.WriteLine("Fixing: " + itemName);
if (!string.IsNullOrEmpty(itemName))
{
string wikiData = item.Attributes["ows_WikiField"].Value;
string actualWikiData = string.Empty;
if (string.IsNullOrEmpty(wikiData))
{
Trace.WriteLine("...using ows_MetaInfo instead of ows_WikiField");
string itemData = item.Attributes["ows_MetaInfo"].Value;
Regex metaProp = new Regex(@"( \w*:\w{2}\|)");
string[] regexData = metaProp.Split(itemData);
/* I am going to use prepnextMatch to say that the next iteration in the loop has the WikiField data if it exists. It was a rare condition where WikiField wouldn’t return it and this method would, and I believe it was caused by the Alpha upgrades that nobody else should have gone through on some of our internal servers. None-the-less, it may be interesting to see this alternate method. */
bool prepnextMatch = false;
foreach (string data in regexData)
{
try
{
if (data != string.Empty)
{
if (!prepnextMatch)
{
if (data == " WikiField:SW|")
{
prepnextMatch = true;
}
}
else if (prepnextMatch && actualWikiData == string.Empty)
{
actualWikiData = data;
break;
}
else
{
throw new System.Exception("E_FAIL");
}
}
}
catch {}
}
}
else
{
actualWikiData = wikiData;
