[英]HtmlAgility remove attribute from style parameter of Div node
I am stuck trying to remove a style definition from the style attribute of a DIV element. 我试图从DIV元素的style属性中删除样式定义。 HTML code:
HTML代码:
<div class="el1" style="width:800px; max-width:100%" />
...
<div class="el2" style="width:800px; max-width:100%" />
There may be more than 1 of these elements that I need to apply the manipulation to. 我需要将这些元素中的一个以上元素应用于操作。
Here is what I have thus far using HtmlAgilityPack. 这是我到目前为止使用的HtmlAgilityPack。
foreach (HtmlNode div in doc.DocumentNode.SelectNodes("//div[@style]"))
{
if (div != null)
{
div.Attributes["style"].Value["max-width"].Remove(); //Remove() does not appear to be a function
}
}
My thought process was to select any with a style attribute. 我的思维过程是选择任何一个样式属性。 Look for a max-width definition and remove it.
查找最大宽度定义并将其删除。
Any guidance on how this can be achieved? 有关如何实现这一目标的任何指导?
THanks Marcel for pointing me to the right direction: 谢谢马塞尔指出我正确的方向:
Here is the solution that worked for me. 这是适合我的解决方案。
HtmlNodeCollection divs = doc.DocumentNode.SelectNodes("//div[@style]");
if (divs != null)
{
foreach (HtmlNode div in divs)
{
string style = div.Attributes["style"].Value;
string pattern = @"max-width(.*?)(;)";
Regex regex = new Regex(pattern, RegexOptions.IgnoreCase);
string newStyle = regex.Replace(style, String.Empty);
div.Attributes["style"].Value = newStyle;
}
}
