I have the following code snippet to read the colorRange attributes for the colorRangeSwatch in the xml file listed
below.
string expr = "/swatches[colorRangeSwatch='All Red Colors']/colorRangeSwatch/colorRange";
XmlElement crsElement = (XmlElement)m_colorRangeSwatchDoc.SelectSingleNode (expr);
bool fr = bool.Parse(crsElement.GetAttribute("fixed").ToStri ng());
The element returned is always the 1st, All Blue Colors, why doesn't the expression filter on the colorRangeSwatch
value?
Any ideas would be welcome.
Thanks,

There are at least three problems:
1. Your source xml is unreadable -- in case you really hope someone might
give it a try, provide a more readable version, maybe something like this:
<swatches id="CustomColorRangeSwatches">
<colorRangeSwatch>All Blue Colors
<colorRange fixed="True"
red="0" green="0" blue="193"
redMin="0" redMax="0"
greenMin="0" greenMax="0"

greenMin="0" greenMax="0"
blueMin="0" blueMax="0" />
</colorRangeSwatch>
</swatches>
2. The comparison:
colorRangeSwatch='All Red Colors'
will most probably return false for the top node. There are some NL
characters after the starting text.
3. Most important:
/swatches[colorRangeSwatch='All Red
Colors']/colorRangeSwatch/colorRange
-------------------------------------------------------------^^^^^^^^^^^^^^^^^^^
Even if the comparison in the predicate returns true, the location
step following it selects *all* "colorRangeSwatch" elements children of the
top element "swatches"
Thus, if the comparison is trye, the expression above will select all
"colorRange" children of all "colorRangeSwatch" children of the top element
"swatches".
Then the SelectSingleNode() method returns the first in document order
such "colorRange" element -- and you say you want the second.
One XPath expression that will select the node you seem to want is:
/swatches/colorRangeSwatch[starts-with(.,'All Red Colors')]/colorRange
Hope this helped.

Thanks, it works. I don't really understand why but it does appear to do what I want. It has been quite frustrating
trying to figure out the right syntax.
Apart from the xml header line I don't see a difference between the xml you returned and what I posted.

Your original XPath expression:
/swatches[colorRangeSwatch='All Red

has this translation into English:
Select all "colorRange" elements that are children of a "colorRangeSwatch"
element, which is a child of a top element named "swatches", if this top
element has children named "colorRangeSwatch", whose string value is 'All

It selects the same nodes as this simpler expression because the condition
inside the predicate is true -- the top element satisfies the condition,
therefore all of its colorRangeSwatch/colorRange grand-children will be
selected:
/swatches/colorRangeSwatch/colorRange
But you wanted the colorRange nodes that are children only of the
colorRangeSwatch elements, whose string value starts with
'All Red Colors'
One XPath expression that returns the nodes you wanted is

Many thanks. I understand what is happening now. I tried quite a few sources for XPath but none of them were really
clear on what was happening in the selection process even though they had quite a few examples. I guess it is always
more difficult when you have to work out an example for the first time.
I hadn't really noticed the functions either. I am surprised though that there does not appear to be a function for
testing equality between two strings.
Thanks again,

> I hadn't really noticed the functions either. I am surprised though that there does not appear to be a function for

There isn't a "function" for comparing two strings, because this function is
the "=" operator.
the expression
str1 = str2,
where str1 and str2 are strings
is true iff the two strings are equal.
I used the starts-with() function, because in your xml file their were some
newline (NL) characters part of the text nodes.
Another way to eliminate unnecessary white space is to use the
normalize-space() function.

redMin="0" redMax="255"
greenMin="0" greenMax="0"

</colorRangeSwatch>
</swatches>
2. The comparison:

You can just use = for that.
