用iTextSharp中的XML Worker替换HTMLWorker

问题描述

目前我正在使用此代码：

Currently I'm using this code :

StyleSheet css = new StyleSheet();
using (var htmlViewReader = new StringReader(htmlText)) {
    using (var htmlWorker = new HTMLWorker(pdfDocument)) {
        css.LoadStyle("body", "style", "width: 100%;");
        //  css.LoadStyle(".fr", "style", "float: right;");
        css.LoadStyle("fr","float","right");
        css.LoadStyle(".fl", "style", "float: left; width: 20%;");
        css.LoadStyle("container", "style", "width: 960px; margin: 0 auto;");
        css.LoadStyle("header", "style", "margin-top: 75px; width: 100%;");
        css.LoadStyle("header name", "style", "font-size: 18px;");
        css.LoadStyle("footer", "style", "border-top: 2px solid #333; text-align: center;");
        css.LoadTagStyle("p", "style", "padding: 0 45px 0 25px; color: #666;");
        css.LoadTagStyle("a", "style", "color: #666;");
        css.LoadStyle("deposit", "style", "font-size: 22px; width: 100%; color: #999; font-weight: bold; float:right;");
        css.LoadStyle("cl", "style", "clear: both;");
        css.LoadStyle("title", "style", "margin: 0 45px 0 25px; border-bottom: 2px solid #333; font-weight: bold;");
        css.LoadTagStyle("ul", "style", "list-style-type: none; width: 50%;");
        css.LoadTagStyle("ul li", "style", "line-height: 25px;");
        css.LoadTagStyle("li", "style", "line-height: 25px;");
        htmlWorker.SetStyleSheet(css);
        //htmlWorker.Parse(htmlViewReader);
    }
}

但是，记录在案的 HTMLWorker 不解析CSS样式。

However, as documented HTMLWorker doesn't parse CSS styles.

我需要用XML Worker替换它。有关如何执行此操作的任何想法？

I need to replace it with XML Worker. Any idea on how to do this?

推荐答案

要将CSS与XML Worker一起使用，您可以从外部css文件加载它：

To use CSS with XML Worker, you can load it from an external css file:

public static class XMLWorkerUtils
{
    public static ICssFile GetCssFile(string filePath)
    {
        using (var stream = new FileStream(filePath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
        {
            return XMLWorkerHelper.GetCSS(stream);
        }
    }
}

或者你可以内联定义它：

Or you can define it inline:

var cssResolver = new StyleAttrCSSResolver();
// cssResolver.AddCss(XMLWorkerUtils.GetCssFile(@"c:\path\pdf.css"));
cssResolver.AddCss(@"code
                         {
                            padding: 2px 4px;
                            color: #d14;
                            white-space: nowrap;
                            background-color: #f7f7f9;
                            border: 1px solid #e1e1e8;
                         }",
                         "utf-8", true);

然后将此cssResolver注入CssResolverPipeline。有关详细信息，请参阅。

Then inject this cssResolver into the CssResolverPipeline. Read more about it in its official documentation here.
