Hello,

I need to know how to use OpenXMLSDK (DocumentFormat.OpenXml.Packaging) to extract slide titles as well as slide texts for all slides in order.

I would appreciate if you can give me some sample code in C# or a relevant tutorial website.

Best regards,

Try this

const string presentationmlNamespace = "http://schemas.openxmlformats.org/presentationml/2006/main";

List<string> titles = new System.Collections.Generic.List<string>();

using (PresentationDocument pptDoc = PresentationDocument.Open(@"C:\users\abhatia\desktop\test.pptx", false))

{

// Manage namespaces to perform Xml XPath queries.

NameTable nt = new NameTable();

XmlNamespaceManager nsManager = new XmlNamespaceManager(nt);

nsManager.AddNamespace("p", presentationmlNamespace);

foreach (SlidePart slidePart in pptDoc.PresentationPart.SlideParts)

{

XmlDocument slideDoc = new XmlDocument(nt);

slideDoc.Load(slidePart.GetStream());

XmlNodeList ss = slideDoc.SelectNodes("//p:sp", nsManager);

foreach (XmlNode w in ss)

{

if (w.SelectSingleNode(".//p:ph", nsManager) != null)

{

string hed = w.SelectSingleNode(".//p:ph", nsManager).Attributes["type"].Value;

// If you want to include subTitle then check for head=="subTitle" as well

if (hed == "title" || hed == "ctrTitle")

// // This is slide Header

MessageBox.Show(w.InnerText);

}

else

{

// This is slide Text

MessageBox.Show(w.InnerText);

}

}

}

}

I was also looking to see how I can get the correct order of the slides and saw this post.   I tested your code but it doesn't seem to put the slides in order.

When you view a presentation in "normal" view you will see the slided in the left pane numbered 1 through x.   How can you get the titles ordered just like that?

Thanks

hi,

the way i did that was to extract and sort the slide ids like rId1,rId13,rId11 etc.
just parse the numeric value of it 1,13,11
sort it
prefix rId again to this sorted slide ids
now process foreach slide

Although I am not sure if the slides are in this order always but when i did a qucik test in office 2007, the random addition and deletion of slides would always put the sldie ids in sequence

thanks

Hi,

Try this code. It extracts the slide text & title in their order.

const string presentationmlNamespace = "http://schemas.openxmlformats.org/presentationml/2006/main";

PresentationDocument presDoc = PresentationDocument.Open(@"C:\users\abhatia\desktop\test.pptx", true);

NameTable nt = new NameTable();

XmlNamespaceManager nsManager = new XmlNamespaceManager(nt);

nsManager.AddNamespace("p", presentationmlNamespace);

XmlDocument presXML = new XmlDocument(nt);

presXML.Load(presDoc.PresentationPart.GetStream());

// Get the rId of the slides present in the Presentation.xml

XmlNodeList ss1 = presXML.SelectNodes("//p:sldId", nsManager);

// Loop thorugh each slide and the slide Part by their rId

foreach (XmlNode w1 in ss1)

{

OpenXmlPart sldPart = presDoc.PresentationPart.GetPartById(w1.Attributes[1].Value);

XmlDocument slideDoc = new XmlDocument(nt);

slideDoc.Load(sldPart.GetStream());

// Get the sp element to read slide text and header

XmlNodeList ss = slideDoc.SelectNodes("//p:sp", nsManager);

foreach (XmlNode w in ss)
{
if ((w.SelectSingleNode(".//p:ph", nsManager) != null) && (w.SelectSingleNode(".//p:ph", nsManager).Attributes["type"] != null))
{
string hed = w.SelectSingleNode(".//p:ph", nsManager).Attributes["type"].Value;

// If you want to include subTitle then check for head=="subTitle" as well

if (hed == "title" || hed == "ctrTitle")
// // This is slide Header

MessageBox.Show(w.InnerText);
}
else
{
// This is slide Text

MessageBox.Show(w.InnerText);

}}}

presDoc.Close();

Hi,
The slide order can only be decided by the order in the presentation.xml of SlideLst Node.

"p:sldIdLst>p:sldId> ... /p:sldId> /p:sldIdLst>"

Try moving the slides inside the presentation and have look into the presentation.xml file. Nothing (like rel Id, slidepart.. ) will be changed except the "p:sldId" order in "p:sldIdLst" node.
