Innertext and XPathNavigator.Value

[Jack Fox]

I'm navigating through a XPathDocument consisting of mostly mixed complex
type elements (i.e. innertext plus more elements). When I use
XPathNavigator.Value to retrieve the text I get everything between <mytag>
and </mytag>, the text I'm looking for, but also all the text portion of
every sub tag (but not the tags themselves).

Is there a method in the MVP XML library or some other work around I can
user to get only the text of the parent tag?

I am not sure I understand what you want exactly (some XML sample would
have helped) but if you want the text of child text nodes then you could
select those e.g. if the navigator is positioned on your mytag element
XPathNodeIterator iterator = navigator.SelectChildren(XPathNodeType.Text);
and use the iterator to get those text node values and concatenate them
(using string concatenation or a StringBuilder if needed) e.g.
string childText = "";
while (iterator.MoveNext()) {
childText += iterator.Current.Value;
}
// now use childText here

The element itself has no text, anything in there is a child node.

<parent>parent text
<child>child text</child>
</parent>

When XPathNavigator is positioned on parent and I look at the Value
property, what I get is "parent textchild text". I want only "parent text".

OK, I figured out how to do this, it requires further XPath selection

XPathNodeIterator s = navCurHeading.Select("text()[1]");

s.MoveNext();

string ss = s.Current.Value;

"navCurHeading is the navigator positioned on your complex node (it has its
own text as well as children nodes with text. The XPath selection selects
the first text node into an iterator. Not quite as simple as I would have
expected, but it works.

Well my suggestion was to select all child text nodes and then
concatenate while iterating. That seems more general. But if you want
only the text of the first child text node then use the above.
