我正在尝试从HTML内容中删除span,font,b,s,strike(和其他内部元素)标记,同时保留其中的文本和<br>
标记。为此,我正在使用HTML敏捷包。我设法保留了文字,但<br>
标签仍然存在问题。有什么想法吗?
以下是代码:
private void removeTagsButPreserveText2(HtmlNode nodeToRemove)
{
var parent = nodeToRemove.ParentNode;
var prev = nodeToRemove.PreviousSibling;
if (prev != null)
{
var child = nodeToRemove.SelectNodes("./br");
if (child == null)
{
parent.InsertAfter(documentToSearch.CreateTextNode(nodeToRemove.InnerText + " "), prev);
nodeToRemove.Remove();
}
else
{
foreach (var item in child)
{
var parent2 = item.PreviousSibling;
if (parent2 != null)
{
if (parent2.InnerText.HasDate())
{
var newNode = parent.InsertAfter(documentToSearch.CreateTextNode(parent2.InnerText), prev);
parent.InsertAfter(documentToSearch.CreateElement("br"), newNode);
nodeToRemove.Remove();
}
}
}
}
}
}
例如,输入将是:
<p><font face="Arial" size="2"><strike>
<span style="font-weight: 400"><font color="#000000">Paper
Submission (Full
Paper) Before
<span lang="en-us">September</span> 20, 201<span lang="en-us">2</span></font></span></strike><font color="#FF0000"><br>
Notification of
Acceptance On <span lang="en-us">October 5</span>, 201<span lang="en-us">2</span><br>
Authors'
Registration Before
<span lang="en-us">October 20</span>, 201<span lang="en-us">2</span><br>
ICNIT 2012 Conference
Dates November
17 - 18, 2012</font></font></p>
,输出应如下所示:
<p>Paper Submission (Full Paper) Before September 20, 2012<br>
Notification of Acceptance On October 5, 2012<br>
Authors' Registration Before October 20, 2012<br>
ICNIT 2012 Conference
Dates November
17 - 18, 2012</p>

您是否尝试使用正则表达式?我的意思是,把所有内容都变成“<xxxx asdasd>
”或类似内容并替换每个“”只维护<BR>
?

对于这种HTML操作,有一个很棒的库叫HTML Agility Pack。
这是一个类似的问题,它将指向正确的方向:Html Agility Pack - Remove element, but not innerHtml
