題
我們使用的第三部分導出應用程序將無法正確呈現段落標記（不包括段落之間的額外行），因此我嘗試使用HtmlAgilityPack將所有段落標記替換為兩個換行標記。
這是我到目前為止所擁有的......
// Shortened for this example
string rawHtml = "<p><strong><span>1.0 Purpose</span></strong></p><p><span>The role</span></p><p><span>NOTE: Defined...</span></p>";
HtmlDocument doc = new HtmlDocument();
HtmlNode.ElementsFlags["br"] = HtmlElementFlag.Empty;
doc.LoadHtml(rawHtml);
doc.OptionWriteEmptyNodes = true;
// Updated using suggestion from Petr
HtmlNode linebreak = doc.CreateElement("br");
var paragraphTags = doc.DocumentNode.SelectNodes("p");
for (int i = 0; i < paragraphTags.Count; i++)
{
HtmlNode childNode = HtmlNode.CreateNode(paragraphTags[i].InnerHtml);
HtmlNode nextNode = paragraphTags[i];
if (i > 0)
{
nextNode = doc.DocumentNode.InsertAfter(linebreak, nextNode);
nextNode = doc.DocumentNode.InsertAfter(linebreak, nextNode);
}
doc.DocumentNode.InsertAfter(childNode, nextNode);
paragraphTags[i].Remove();
}
它確實刪除了段落標記，但只渲染了一個換行符。我已經搜索了互聯網以獲得盡可能多的東西，但似乎沒有任何效果。
OuterHtml看起來像這樣....
// Shortened for this example
string rawHtml = "<p><strong><span>1.0 Purpose</span></strong></p><p><span>The role</span></p><p><span>NOTE: Defined...</span></p>";
HtmlDocument doc = new HtmlDocument();
HtmlNode.ElementsFlags["br"] = HtmlElementFlag.Empty;
doc.LoadHtml(rawHtml);
doc.OptionWriteEmptyNodes = true;
// Updated using suggestion from Petr
HtmlNode linebreak = doc.CreateElement("br");
var paragraphTags = doc.DocumentNode.SelectNodes("p");
for (int i = 0; i < paragraphTags.Count; i++)
{
HtmlNode childNode = HtmlNode.CreateNode(paragraphTags[i].InnerHtml);
HtmlNode nextNode = paragraphTags[i];
if (i > 0)
{
nextNode = doc.DocumentNode.InsertAfter(linebreak, nextNode);
nextNode = doc.DocumentNode.InsertAfter(linebreak, nextNode);
}
doc.DocumentNode.InsertAfter(childNode, nextNode);
paragraphTags[i].Remove();
}
知道我做錯了什麼嗎？我覺得有一個更簡單的方法，是嗎？
一般承認的答案
弄清楚了。向Petr和Simon提出建議。關鍵似乎是我需要兩個不同的換行節點。
string rawHtml = "<p><strong><span>1.0 Purpose</span></strong></p><p><span>The role</span></p><p><span>NOTE: Defined...</span></p>";
HtmlDocument doc = new HtmlDocument();
HtmlNode.ElementsFlags["br"] = HtmlElementFlag.Empty;
doc.LoadHtml(rawHtml);
doc.OptionWriteEmptyNodes = true;
HtmlNode linebreak1 = doc.CreateElement("br");
HtmlNode linebreak2 = doc.CreateElement("br");
var paragraphTags = doc.DocumentNode.SelectNodes("p");
for (int i = 0; i < paragraphTags.Count; i++)
{
if (i > 0)
{
doc.DocumentNode.InsertBefore(linebreak1, paragraphTags[i]);
doc.DocumentNode.InsertBefore(linebreak2, paragraphTags[i]);
}
doc.DocumentNode.InsertBefore(HtmlNode.CreateNode(paragraphTags[i].InnerHtml), paragraphTags[i]);
paragraphTags[i].ParentNode.RemoveChild(paragraphTags[i]);
}
