HtmlAgilityPack set node InnerText

问题

I want to replace inner text of HTML tags with another text. I am using HtmlAgilityPack
I use this code to extract all texts

HtmlDocument doc = new HtmlDocument();
doc.Load("some path")

foreach (HtmlNode node in doc.DocumentNode.SelectNodes("//text()[normalize-space(.) != '']")) {
    // How to replace node.InnerText with some text ?
}

But InnerText is readonly. How can I replace texts with another text and save them to file ?

回答1:

Try code below. It select all nodes without children and filtered out script nodes. Maybe you need to add some additional filtering. In addition to your XPath expression this one also looking for leaf nodes and filter out text content of <script> tags.

var nodes = doc.DocumentNode.SelectNodes("//body//text()[(normalize-space(.) != '') and not(parent::script) and not(*)]");
foreach (HtmlNode htmlNode in nodes)
{
    htmlNode.ParentNode.ReplaceChild(HtmlTextNode.CreateNode(htmlNode.InnerText + "_translated"), htmlNode);
}

Strange, but I found that InnerHtml isn't readonly. And when I tried to set it like that

aElement.InnerHtml = "sometext";

the value of InnerText also changed to "sometext"
