XML and quote

[mtugnoli]

This is my XML file

<?xml version="1.0" encoding="utf-8"?>
<index>
<folder Name="Test1">
<folder Name="Test2">
<files>
<file Name="After You've Gone.mp3"/>
<file Name="Prova.mp3 "/>
</files>
</folder>
</folder>
</index>
nodeSel = doc.SelectSingl eNode"/index/folder[@Name='Test1']/
folder[@Name='Test2']/files/file[@Name='After You've Gone.mp3']");
and this function make me error, to token not valid

I think the problem is the quote in : "After You've Gone.mp3"
how have to do ?
Thank you

Marco

Unfortunately that is difficult to achieve with XPath 1.0 as it does not
allow you to escape characters, rather all it allows is breaking up the
string into sequences you concatenate e.g.
doc.SelectSingl eNode("/index/folder[@Name='Test1']/
folder[@Name='Test2']/files/file[@Name= concat('After You', \"'\", 've
Gone.mp3')]")
Thus if someone passes you the @Name value as a string you will have to
write code with C# that breaks up the string into pieces not containing
single quotes and containing single quotes to convert into one string
that uses the XPath concat function to concatenate pieces delimited by
single quotes with pieces delimited by double quotes as in the above
example.

Thanks Martin,
I usually “guard” my code in the C#, but this technique seems more
effective.
