Debugging Aspose Errors

[aron]

Below is some code that works fine in general, however it's throwing an error on the attached document.

Is there any way to view the node tree of a document through Aspose.Words. We use Aspose & I often run into errors. I find it very hard to debug, since I don't know exactly why the error is happening. Below is one example. Is there any way for me to debug this on my own, or should I continue posting in the forums?

The following code throws an error on the attached document

• private static string GetHtmlFromBookmark(string bookmarkName, Document doc, SaveFormat ThisSaveFormat)
• {
• Document docClone = doc.Clone();
• Document doc1 = new Document();
• Bookmark mark = docClone.Range.Bookmarks[bookmarkName];
• Node node = mark.BookmarkStart.ParentNode;
• Node endNode = mark.BookmarkEnd.ParentNode.NextSibling;
• while (!node.Equals(endNode))
• {
• if ((node as CompositeNode).ChildNodes.Contains(mark.BookmarkStart))
• {
• Node child = (node as CompositeNode).FirstChild;
• Node endChild = mark.BookmarkStart.NextSibling;
• while (!child.Equals(endChild))
• {
• child = child.NextSibling;
• child.PreviousSibling.Remove();
• }
• }
• if ((node as CompositeNode).ChildNodes.Contains(mark.BookmarkEnd))
• {
• Node child = mark.BookmarkEnd;
• while (!child.Equals(child.ParentNode.LastChild))
• {
• child = child.NextSibling;
• child.PreviousSibling.Remove();
• }
• child.Remove();
• }
• doc1.FirstSection.Body.AppendChild(doc1.ImportNode(node, true, ImportFormatMode.KeepSourceFormatting));
• node = node.NextSibling;
• if (node == null)
• break;
• }
• MemoryStream stream = new MemoryStream();
• doc1.Save(stream, ThisSaveFormat);
• string html = Encoding.UTF8.GetString(stream.GetBuffer());
• return html;
• }

Hi<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Thanks for your request. I modified your code and now it should work fine:

private static string GetHtmlFromBookmark(string bookmarkName, Document doc, SaveFormat ThisSaveFormat)

{

Document docClone = doc.Clone();

Document doc1 = new Document();

Bookmark mark = docClone.Range.Bookmarks[bookmarkName];

Node node = mark.BookmarkStart.ParentNode;

Node endNode = mark.BookmarkEnd.ParentNode.NextSibling;

while (!node.Equals(endNode))

{

if ((node as CompositeNode).ChildNodes.Contains(mark.BookmarkStart))

{

Node child = (node as CompositeNode).FirstChild;

Node endChild = mark.BookmarkStart.NextSibling;

if (child != null && endChild != null)

{

while (!child.Equals(endChild))

{

child = child.NextSibling;

child.PreviousSibling.Remove();

}

}

}

if ((node as CompositeNode).ChildNodes.Contains(mark.BookmarkEnd))

{

Node child = mark.BookmarkEnd;

while (!child.Equals(child.ParentNode.LastChild))

{

child = child.NextSibling;

child.PreviousSibling.Remove();

}

child.Remove();

}

doc1.FirstSection.Body.AppendChild(doc1.ImportNode(node, true, ImportFormatMode.KeepSourceFormatting));

node = node.NextSibling;

if (node == null)

break;

}

MemoryStream stream = new MemoryStream();

doc1.Save(stream, ThisSaveFormat);

string html = Encoding.UTF8.GetString(stream.GetBuffer());

return html;

}

Best regards.
