自己做这件事真的很简单。您没有指定语言，因此下面的示例使用 VB.Net，因为（我认为）它更容易处理 XML。有关详细信息，请参阅代码注释。这是针对 iTextSharp 5.4.4，但应该适用于几乎任何版本。
''//Sample XML
Dim TextXML = <?xml version="1.0" encoding="utf-8"?>

Using doc As New Document()
Using writer = PdfWriter.GetInstance(doc, fs)
doc.Open()

这是一个 C# 版本。我已经包含了一个帮助方法来根据您的模板创建一个大型 XML 文档以显示页面溢出。将PdfPTable自动向多个页面发送垃圾邮件。您可以指定应被视为“标题”的行数，以便它们在后续页面上重复。您可能还想应用一些格式规则，但您应该能够在网上找到这些规则（查找PdfPTable.DefaultCell）
private XDocument createXml() {
//Create our sample XML document
var xml = new XDocument(new XDeclaration("1.0", "utf-8", "yes"));
//Add our root node
var root = new XElement("catalog");
//All child nodes
var nodeNames = new[] { "SR.No", "test", "code", "unit", "sampleid", "boreholeid", "pieceno" };
XElement cd;
//Create a bunch of <cd> items
for (var i = 0; i < 1000; i++) {
cd = new XElement("cd");
foreach (var nn in nodeNames) {
cd.Add(new XElement(nn) { Value = String.Format("{0}:{1}", nn, i.ToString()) });
}
root.Add(cd);
}
xml.Add(root);
return xml;
