Probably, looking up the schema is a good idea and I am not at all against it. The problem is, that mingling xpath with schema to create missing nodes via dom is something extremely complicated. I wouldn't even know where to start.
That's why I thought, that XUpdate would help me there, as it is an developed language for more or less this purpose. At least I am thinking it is. I just looked it up a few days ago and haven't found anything better since. But I have no idea, if XUpdate does not have any pitfalls I am not aware of, if the implementation, I found, is ok and most importantly, if there isn't some other, more straight forward way.
As for explaining my somewhat confusing (I admit) text:
I wrote a provider that allows me to update and delete nodes via xpath. That's something quite easy. Now I needed to insert nodes as well and as the xpath was something I already had in my classes, I tried to implement the insert as well via xpath. I failed at that and I am pretty sure that xpath just is not the right expression for the job.
Even though others at cp have tried something quite similar: http://www.codeproject.com/csharp/xpathstore.asp
So my examples have to be read with that bias: to use an xpath as an more or less equivalent to an sql insert statement.
I query: /foo/bar[action='4']/element
Now, this node does not exist, so it should be created (and it's predecessor bar with the attribute action=4). foo exists, so nothing needs to be done for it.
Same aplies for /foo/bar[4]/element, just the attribute has to come from somewhere else (I can provide for this).
/foo/bar[5]/element should fail (because there is no element bar[4] for it to be inserted after)
Thanks for sharing your thoughts!

Ummm this is the XML/XSL forum and your questions, as stated, do not appear to pertain to either one of them since neither have a "page".
Try this[^]

Well I believe most people on Code Project are not psychic so unless you tell us "pdf" we don't know. So your question is a PDF question. How are you generating PDF from XML using XSL, are you using FO? I may know someone that I can ask if that is the case.

yes i'm using fop. i use page break after every tag called "TEST". This results in a blank page at the end since i have to close the "TEST" tag at the end. How do i remove this blank page if it is possible?
Thanks for your time...

you should be able to do something like
<xsl:if test="not(position() = last())">
<!-- insert the page break FOP whatever -->
</xsl:if>

Hi all,
How do you put a footer on each page sequence?
I have for each x amount of rows in a table a new page sequence, but what is the code snippet for inserting a footer...?
Thank you in advance...

I'm pretty new to programming XML on .NET. I'm looking for best practices on constructing an XML document.
Do I have anything to gain by building an XML document with a StringBuilder and then converting it to an XmlDocument? Should I just create the document using the proper objects as I go along? Any other tips?
Thanks,

Edit: Upon further investigation, it looks like XmlTextWriter is what I'm after.

string PI= "type='text/xsl' href='Whatever.xsl'";
XmlTextWriter myXmlTextWriter = new XmlTextWriter("PATH.xml", null);
myXmlTextWriter.Formatting = Formatting.Indented;
myXmlTextWriter.WriteStartDocument();
myXmlTextWriter.WriteProcessingInstruction("xml-stylesheet", PI);
//Open tag.
myXmlTextWriter.WriteStartElement("TagName");
//Open Tag with Attribute.
myXmlTextWriter.WriteStartElement("TagName2",null);
myXmlTextWriter.WriteAttributeString("key", Convert.ToString(counter));
//StartTagAndEndTagWithValue
myXmlTextWriter.WriteElementString("TagName3","What You Want Between Tags");
//Close Tag. This One Closes the "TagName2".
myXmlTextWriter.WriteEndElement();
//Close Tag. This One Closes the "TagName".
myXmlTextWriter.WriteEndElement();
//Write the XML to file(Look at "PATH.xml" part at the top)and close the myXmlTextWriter
myXmlTextWriter.Flush();
myXmlTextWriter.Close();
Hope that it is of some help...

We have been bitten by severe memory leaks in our project.
While having a dry run of one of the components code. I came across the following. This looks like a sure shot memory leak to me. Because of the fact that we are not doing a VariantClear().
Please confirm.
<<
try
{
IXMLDOMSchemaCollection2Ptr m_pSchemaCache;
hr=m_pSchemaCache.CreateInstance(__uuidof(MSXML2::XMLSchemaCache60));
if (SUCCEEDED(hr))
{
hr=m_pSchemaCache->add(szNameSpace_in, szSchemaFilePath_in);
if (SUCCEEDED(hr))
{
VARIANT varValue;
varValue.vt = VT_DISPATCH;
varValue.pdispVal = m_pSchemaCache.GetInterfacePtr();
m_pSchemaCache.AddRef();
m_pDOMDoc->PutRefschemas(varValue);
}
else
{
this->m_errorCode=ERR_XML_DOC_SCHEMA_ADDITION_FAILED;
return FALSE;
}
}
else
{
this->m_errorCode=ERR_XML_DOC_SCHEMA_INSTANCE_CREATION_FAILED;
}
}

Hi All,
I have a XML string with me in the format
<row xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<SEQNO>6</SEQNO>
<B_CO_CD>H</B_CO_CD>
<B_AREA_CD>K</B_AREA_CD>
</row>
the XML tags are taken in an actual string variable and then I need to find a particular tag and get its value to actually set that value in a dataset column that corresponds to this tag.
How can I do this ??
Pls guide me.. I need to give demo on this..Pls Pls

 Hi Omkar,
find below the code to get value in a particular tag.
System.Data.DataSet ds=new DataSet();
ds.ReadXml("D:\\MY_WORK\\ssis projects\\Executessis\\WindowsApplication1\\XMLFile1.xml");//here set your xml file path
int i=ds.Tables[0].Columns["SEQNO"].Ordinal;//getting the position of the column/tag
string s=ds.Tables[0].Rows[0].ItemArray.GetValue(i).ToString();//getting the actual vlaue inside the tag
Tell me if it will not work...

Hi,
I have a directory containing loads of xml files that change regularly. To generate a list of all the files in the directory i use this code:
Sub Page_Load(sender as Object, e as EventArgs)<br />
If Not Page.IsPostBack then<br />
Dim dirInfo as New DirectoryInfo(Server.MapPath(""))<br />
repeater.DataSource = dirInfo.GetFiles("*.xml")<br />
repeater.DataBind()<br />
End If<br />
End Sub
I then display this information in a asp repeater. Currently it lists the filename and size and when the document was last edited.
I wish to extend this concept to allow me to display the 'title' element of each xml file alongside the filename in my asp repeater. I know how to extract the 'title' from a static list of xml files by explicity binding to each one, but i dont know how to do this 'on the fly' with the xml files in my generated list. I hope that made relative sense to somebody.
Thanks alot.
Colm.
