元素内部类CSS定义不适用使用ITextSharp（5.5.1）XHTML到PDF [英] Element inside class CSS definition not applied using ITextSharp (5.5.1) XHTML to PDF
问题描述
更新：ITextSharp 5.5.2支持此功能，但以前版本的ITextSharp不支持。
ITextSharp 5.5.1支持类元素CSS选择器？如
Does ITextSharp 5.5.1 support Class Element CSS selectors? Such as
<style>
.test td {
border: 1px solid green;
}
</style>
我得到了这样的结果
喜欢
如果不是，我将如何获得相同的结果？
使用以下代码获得所需的结果。
Using the following code I do not get the desired results.
byte[] bytes;
Document document = new Document();
using (var memoryStream = new MemoryStream())
using (var pdfWriter = PdfWriter.GetInstance(document, memoryStream))
{
document.Open();
XMLWorkerHelper.GetInstance().ParseXHtml(pdfWriter, document, new StringReader(html));
document.Close();
bytes = memoryStream.ToArray();
}
return bytes;
这是我的完整html参考
Here is my full html for reference
<html>
<head>
<style>
.test td {
border: 1px solid green;
}
</style>
</head>
<body>
<table class='test'>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Savings</th>
</tr>
<tr>
<td>Peter</td>
<td>Griffin</td>
<td>$100</td>
</tr>
<tr>
<td>Lois</td>
<td>Griffin</td>
<td>$150</td>
</tr>
<tr>
<td>Joe</td>
<td>Swanson</td>
<td>$300</td>
</tr>
<tr>
<td>Cleveland</td>
<td>Brown</td>
<td>$250</td>
</tr>
</table>
</body>
</html>
推荐答案
这是一个奇怪的问题，因为XML的默认实现工人完全按照你的需要。我们有一个HTML文件 table_css.html 转换为 html_table_3.pdf ，我们只使用基本的XML Worker代码： ParseHtmlTable3
This is a strange question since the default implementation of XML Worker does exactly what you need. We have an HTML file table_css.html that is converted to html_table_3.pdf and we use nothing more than the basic XML Worker code: ParseHtmlTable3
您只需要5行来实现屏幕截图中显示的结果：
You only need 5 lines to achieve the result shown in the screen shot:
public void createPdf(String file) throws IOException, DocumentException {
// step 1
Document document = new Document();
// step 2
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(file));
// step 3
document.open();
// step 4
XMLWorkerHelper.getInstance().parseXHtml(writer, document,
new FileInputStream(HTML));
// step 5
document.close();
}
