I have the following HTML:
<div class="top"> <p>Blah.</p> I want <em>this</em> text. </div>
What is the XPath notation to extract the string "
I want <em>this</em> text."?
EDIT: I don't necessarily want a single XPath expression to extract the string. Selecting multiple nodes, and iterating over them to produce the sentence, would be great as well.
HtmlDocument doc = new HtmlDocument(); doc.LoadHtml(myHtml); doc.DocumentNode.SelectSingleNode("??????");
What do you want to extract, nodes or a string?
If you want nodes,
"I want <em>this</em> text." is an XML fragment consisting at the top level of two text nodes and an
<em> element, which has a text node child. Since it has multiple nodes at the top level, you need to use
SelectNodes("xpath expression a la @Alejandro") rather than
SelectSingleNode() to extract them.
If you want a string, again you need to use SelectNodes(); and then iterate over the selected nodes and concatenate the outerHTML of each one. See here for a good example of something similar.
Also, it's a little unclear from your example what XPath expression would in general give you what you want. E.g. do you want everything after the initial
<div class="top">? Or do you want all text under the
<div> except all
<p> elements? Or maybe something else? Of course if @Alejandro's XPath expressions work for you then it's already well-specified enough.
