Apose.Words ImportNode ignores font formatting when appendingchild

I am currently using Aspose.Words to open a document, pull content between a bookmark start and a bookmark end and then place that content into another document. The issue that I'm having is that when using the ImportNode method is imports onto my document but changes all of the fonts from Calibri to Times New Roman and changes the font size from whatever it was on the original document to 12pt.
The way I'm obtaining the content from the bookmark is by using the Aspose ExtractContent method.
Because I'm having the issue with the ImportNode stripping my font formatting I tried making some adjustments and saving each node to an HTML string using ToString(HtmlSaveOptions). This works mostly but the problem with this is it is stripping out my returns on the word document so none of my text has the appropriate spacing. My returns end up coming in as HTML in the following format
"<p style=\"margin-top:0pt; margin-bottom:8pt; line-height:108%; font-size:11pt\"><span style=\"font-family:Calibri; display:none; -aw-import:ignore\"> </span></p>"
When using
DocumentBuilder.InsertHtml("<p style=\"margin-top:0pt; margin-bottom:8pt; line-height:108%; font-size:11pt\"><span style=\"font-family:Calibri; display:none; -aw-import:ignore\"> </span></p>");
it does not correctly add the return on the word document.
Here is the code I'm using, please forgive the comments etc... this has been my attempts at correcting this.

Saving each node to HTML and then inserting them into the destination document is not a good idea. Because not all nodes can be properly saved to HTML and some formatting can be lost after Aspose.Words DOM -> HTML -> Aspose.Words DOM roundtrip.
Regarding the original issue, the problem might occur because you are using ImportFormatMode.UseDestinationStyles, in this case styles and default of the destination document are used and font might be changed. If you need to keep the source document formatting, you should use ImportFormatMode.KeepSourceFormatting.
If the problem occurs even with ImportFormatMode.KeepSourceFormatting this must be a bug and you should report this to Aspose.Words staff in the support forum.

The OpenXML SDK Productivity tool (downloadable from the Microsoft site) is your friend here. When I need to do something like this, I:
Create the document I want
Open it in the appropriate tool (PowerPoint in this case).
Make a tiny change (to "dirty" the document and make PowerPoint believe it needs to be changed).
Save the result
Make the changes to the document that I want to see, and save the result with a new name
Open the OpenXML Productivity Tool and click the "Compare Files" tool.
The reason I force a save (in steps 3/4) is so that PowerPoint can add all of it's PowerPoint-ness to the document I created. The second save (step 5) will necessarily have all of that, so I want the two documents as close as possible - with only the "changes to the document that I want to see" being the difference between the two documents.
At this point, you should see a path to a solution to your problem. That tool is indispensable when working with OOXML.

Aspose PDF - get text from page that has a matching string

I'm working with an existing library - the goal of the library is to pull text out of PDFs to verify against expected values to quality check recorded data vs data in pdf.
I'm looking for a way to succinctly pull a specific page worth of text given a string that should only fall on that specific page.
var pdfDocument = new Document(file.PdfFilePath);
var textAbsorber = new TextAbsorber{
ExtractionOptions = {
FormattingMode = TextExtractionOptions.TextFormattingMode.Pure
}
};
pdfDocument.Pages.Accept(textAbsorber);
foreach (var page in pdfDocument.Pages)
{
}
I'm stuck inside the foreach(var page in pdfDocument.Pages) portion... or is that the right area to be looking?

Answer: Text Absorber recreated each page - inside the foreach loop.
If the absorber isn't recreated, it keeps text from previous loops.
public List<string> ProcessPage(MyInfoClass file, string find)
{
var pdfDocument = new Document(file.PdfFilePath);
foreach (Page page in pdfDocument.Pages)
{
var textAbsorber = new TextAbsorber {
ExtractionOptions = {
FormattingMode = TextExtractionOptions.TextFormattingMode.Pure
}
};
page.Accept(textAbsorber);
var ext = textAbsorber.Text;
var exts = ext.Replace("\n", "").Split('\r').ToList();
if (ext.Contains(find))
return exts;
}
return null;
}

presentationPart.Presentation.Save();
}
the file is saved with required data but
While opening the powerpoint I get the following error:
Powerpoint found a problem with content in "Sample.pptx". Power point can attempt to repair the presentation.
Once repaired, the content is shown ok. but since the file is corrupted when i run the code it is not updating with the latest data nexttime.
Please help me to solve the issue
-tried to open in different version of office but no luck
-created the template from different versions still the issue occurs

Removing jquery and CSS from an Xml Document

I'm using sgmlreader to convert HTML to XML. The output goes into a XmlDocument object, which I can then use the InnerText method to extract the plain text from the website. I'm trying to get the text to look as clean as possible, by removing any javascript. Looping through the xml and removing any <script type="text/javascript"> is easy enough, but I've hit a brick wall when any jquery or styling isn't encapsulated in any tags. Can anybody help me out?
Sample Code:
Step one:
Once I use the webclient class to download the HTML, I save it, then open the file with the text reader class.
Step two:
Create sgmlreader class and set the input stream to the text reader:
// setup SGMLReader
Sgml.SgmlReader sgmlReader = new Sgml.SgmlReader();
sgmlReader.DocType = "HTML";
sgmlReader.WhitespaceHandling = WhitespaceHandling.All;
sgmlReader.CaseFolding = Sgml.CaseFolding.ToLower;
sgmlReader.InputStream = reader;
// create document
doc = new XmlDocument();
doc.PreserveWhitespace = true;
doc.XmlResolver = null;
doc.Load(sgmlReader);
Step three:
Once I have a xmldocument, I use the doc.InnerText to get my plain text.
Step four:
I can easy remove JavaScript tags like so:
XmlNodeList nodes = document.GetElementsByTagName("text/javascript");
for (int i = nodes.Count - 1; i >= 0; i--)
{
nodes[i].ParentNode.RemoveChild(nodes[i]);
}
Some stuff still slips through. Heres an example of an ouput for one particular website I'm scriping:
Criminal and Civil Enforcement | Fraud | Office of Inspector General | U.S. Department of Health and Human Services
#fancybox-right {
right:-20px;
}
#fancybox-left {
left:-20px;
}
#fancybox-right:hover span, #fancybox-right span
#fancybox-right:hover span, #fancybox-right span {
left:auto;
right:0;
}
#fancybox-left:hover span, #fancybox-left span
#fancybox-left:hover span, #fancybox-left span {
right:auto;
left:0;
}
#fancybox-overlay {
/* background: url('/connections/images/wc-overlay.png'); */
/* background: url('/connections/images/banner.png') center center no-repeat; */
}
$(document).ready(function(){
$("a[rel=photo-show]").fancybox({
'titlePosition' : 'over',
'overlayColor' : '#000',
'overlayOpacity' : 0.9
});
$(".title-under").fancybox({
'titlePosition' : 'outside',
'overlayColor' : '#000',
'overlayOpacity' : 0.9
})
});
That jquery and styling needs to be removed.

I just threw this together in LinqPad based on the html of this page and it properly removes the script and style tags.
void Main()
{
string htmlPath = #"C:\Users\Jschubert\Desktop\html\test.html";
var sgmlReader = new Sgml.SgmlReader();
var stringReader = new StringReader(File.ReadAllText(htmlPath));
sgmlReader.DocType = "HTML";
sgmlReader.WhitespaceHandling = WhitespaceHandling.All;
sgmlReader.CaseFolding = Sgml.CaseFolding.ToLower;
sgmlReader.InputStream = stringReader;
// create document
var doc = new XmlDocument();
doc.PreserveWhitespace = true;
doc.XmlResolver = null;
doc.Load(sgmlReader);
List<XmlNode> nodes = doc.GetElementsByTagName("script")
.Cast<XmlNode>().ToList();
var byType = doc.SelectNodes("script[#type = 'text/javascript']")
.Cast<XmlNode>().ToList();
var style = doc.GetElementsByTagName("style").Cast<XmlNode>().ToList();
nodes.AddRange(byType);
nodes.AddRange(style);
for (int i = nodes.Count - 1; i >= 0; i--)
{
nodes[i].ParentNode.RemoveChild(nodes[i]);
}
doc.DumpFormatted();
stringReader.Close();
sgmlReader.Close();
}
Casting to XmlNode to use the generic list is not ideal, but I did it for the sake of space and demonstration.
Also, you shouldn't need both
doc.GetElementsByTagName("script") and
doc.SelectNodes("script[#type = 'text/javascript']").
Again, I did that for the sake of demonstration.
If you have other scripts and you only want to remove JavaScript, use the latter. If you're removing all script tags, use the first one. Or, use both if you want.
