Hi,
In a XML file i want read a tag and search for word. Below is the XML format of the powerpoint(pptx) slide. In which i want search text in a slide which comes under the tag
<a:t xmlns:a="#unknown">TEXT IN A POWERPOINT SLIDE

So, is there any way to only searching for <a:t xmlns:a="#unknown"> tag? Using XPATH will not work on this XML format.
Could any body help me on this?

Why don't you just plain search?

Plain search may return some unwanted result

Why XPATH does not work? What makes you thinking so?

Will it work? I am not sure. Because schema will be different for different xml files... How to trace in to the tag a:t because Textbody may appear anywhere in the xml according to the slide design. Or am I wrong in understanding XPATH??

Hi,

Please clearly tell me that, you need to find a tag(element) or a particular tag values in that xml file? so that i can give some good solutions.

I need to find text inside the tag...
Any way I am able to read the slides text content in XML format by:

XmlDocument dom = new XmlDocument();
dom.Load(xmlfile);
string text = dom.InnerText;

Let's breakdown the search process, then create the search function in C#
1.) What are we looking for?
2.) Where in the file do we THINK it might be? (top, bottom, left, right, upside down?)...etc
3.) search that location
4.) IF your desired substring isn't found then search the whole file, IF it is in fact FOUND, then get the text from inside of our XML tags.
I don't have the code for this but that might or might not help you out.
Anyways, here's some links you might try:

Large XML Files Processing and Indexing[^]

Oh, and...
Try breaking the XML file into 2 parts, and search both subfiles at the same time and that might help on search time.

this link will help you split the xml file into smaller sub files.
