Case insensitive XPath

XPath statements are case sensitive. To get around this use the following example to convert all data to lower case before performing the equality check:

/bookstore/book[translate(@category, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz') = '" + searchtext.ToLower() + "']

Thanks very much to Harish for this!

Hi,

I am getting an XPAth expression an an input from a text box as a string and then using the string to make an XPAth search. How can I use this tranlate func() there to make my search case insensitive. I am working in C# .Net.

<?xml version="1.0"?>

<bookstore specialty="novel">
<book>
<Title>Beginning XML</Title>
<Publisher>Wrox</Publisher>
</book>
<book>
<Title>Professional XML</Title>
<Publisher>Wrox</Publisher>
</book>
<book>
<Title>Programming ADO</Title>
<author>

<last-name>Bob</last-name>
</author>
<datePublished>1/1/2000</datePublished>
<Publisher>Microsoft Press</Publisher>
</book>
</bookstore>

This xpath converts the title to lower case and searches for 'xml' in the Title element and returns all the book Nodes for that title

/bookstore/book/Title[lower-case(.)[contains(.,'xml')]]

Thanks vk, I was getting problems with retrieving nodesets and converting them to upper-case for string comparison, which you obviously can't do.
Your workaround gets round it by converting each node's value within the [] brackets and so I can evaluate my string inside there.

I really loved reading your blog. It was very well authored and easy to understand. Unlike additional blogs I have read which are really not good. I also found your posts very interesting. In fact after reading, I had to go show it to my friend and he enjoyed it as well!
