Hello,
I have a problem by using xpath.

Here is my Xpath:
path="form/document[contains(.,'<%= request.Form("txtSearch")%>')]//*";

If I run that code, I just can search only one word or the exact word.

For example, in my XML file, only available "black","board" and "white board"
If I type "black board" with that code, It shows nothing.

So, I want to know, how if I type "black board", the content of my XML file appear because the program will run the word with "black" + "board" + "black board".

Thanks

XPath 2.0 supports regular expressions.
With XPath 1.0 you can use the boolean operators 'or' or 'and' e.g.
So you will have to build such an XPath expression in your server-side code.

Well, you can tokenize the input, search for each of the terms separately, and combine the results. But I don't think you can do this in a single XPath expression, even with XPath 2.0.

You're becoming more ambitious, but I don't think you have a clear view of the road ahead. It would be a good idea to read something about free-text retrieval systems (for example the XQuery/XPath full text specification at http://www.w3.org/TR/xquery-full-text/) and decide how far you want to go down the road to implementing fully-featured text retrieval. Alternatively, you might consider implementing a software package that does the job well, rather than doing it in a half-hearted way "by hand".

It runs very well. Thanks a lot =)

But, if I change 'doc' and 'pdf' with the variable that I get when user type the word, it showed nothing=(

Here is what I mean:
path="form/document[contains(.,'<%= request.Form("txtSearch")%>') or contains(.,'<%= request.Form("txtSearch")%>')]//*";

It runs very well if I change like this:
path="form/document[contains(.,'pdf') or contains(.,'doc')]//*";

Help me please...

Assuming you use VBScript and classic ASP on the server then you need to split Request.Form("txtSearch") with the proper VBScript code.
VBScript is documented here: http://msdn.microsoft.com/en-us/libr...8VS.85%29.aspx

Hello, I tried again and it works =)

Thanks a lot

:)

Hello, I was wrong...

When I tried :
path="form/document[contains(.,'<%= request.Form("txtSearch")%>')]//*";

It works well.

But when I tried this:
path="form/document[contains(.,'<%= request.Form("txtSearch")%>') and contains(.,' ') or contains(.,'<%= request.Form("txtSearch")%>')]//*";

It was also works well BUT it shows all the xml data. Not only "black" "board" or "black board" but also all xml data.

Help me please.

Use VBScript string processing functions like Split to split Request.Form("txtSearch") and build up an XPath expression.

I would have said your two expressions are equivalent

(A and B or A)

means exactly the same as

(A)

This is assuming there's nothing peculiar about

request.Form("txtSearch")

As has been said umpteen times on this thread, the debugging would be easier if you showed us the XPath expression you are executing, not the code that generates it.

What do you mean by
 

Show XPath expression that I'm executing?

And do you know the "split" code?

Can you show me the example / the code?
