将简单的HTML转换为RichTextBlock [英] Convert simple HTML to a RichTextBlock
问题描述
我从Windows 8开始，尝试将HTML转换为 RichTextBlock 。
I < a href =https://stackoverflow.com/questions/11491134/how-to-show-basic-html-windows8-metro-style-textblock>已阅读，我可以使用此功能： HtmlUtilities.ConvertToText 在一个 TextBlock 中，但是我找不到在 RichTextBlock ！
从我的理解和尝试我无法扩展 RichTextBlock ，所以我无法应用此功能每次调用一个 RichTextBlock 。
此外，我找不到任何方法将文本绑定到 RichTextBlock 和建立一个解析器只是为了简单的HTML（我只想要段落和斜体/粗体）似乎是一种矫枉过正。此外，我不知道应该在哪里解析，因为 RichTextBlock 似乎无法使用。
我可以' t使用 编辑 @mydogisbox让我看到我对自己的感觉太过分了研究。 我可以使用 然而 我最终使用了 package在gitHub上可用，可以将HTML从HTML转换为RickTextBlock。 Basiclly你只需要打开程序包管理器控制台（工具>程序包程序包管理器>程序包管理器控制台）和安装程序包运行 WebView ，因为我需要透明度（并且从我读过的 WebView没有它）。
HtmlUtilities.ConvertToText 来获取属性的getter，我可以在 RichTextBlock 。我无法绑定它，因为我试图做
< Run Text ={Binding TextHTML}/> ，而没有<段落> 标记。
HtmlUtilities.ConvertToText 不会保留斜体或粗体。只有段落：/。
Install-Package RichTextBlock.Html2Xaml 。
xmlns：rtbx =using：EventTests.Common
然后，您可以使用HTML绑定您的属性：
< RichTextBlock rtbx：Properties.Html ={Binding ...}/>
一些问题和一些解决方案
我在这个库中发现的一个问题是它如何处理没有div的简单html。像：
< p>测试< i>斜体< / i>等等。< / p>
< p>更多测试< / p>
打印：
测试斜体等等。
更多测试
然而，我想要这样的东西：
测试 italic 等等。
更多测试
所以我不得不将第二段换成div（除了第一段以外的所有段落都可以被换行）。
< p>测试< i>斜体< / i>等等。< / p>
< div>< p>更多测试< / p>< / div>
如果您换行第一段，那么您将会有一个额外的新行。
到目前为止，这是我找到的最佳解决方案。如果你觉得更好，我会在测试和学习之后加以补充。如果你找到更好的解决方案，我会接受你的。
请小心
如果您有像<的符号，这种方法会崩溃或&在你的HTML。我建议你在尝试使用这个库之前替换这些字符。
I am starting with Windows 8 and I am trying to convert HTML to a RichTextBlock.
I have read that I could use this function : HtmlUtilities.ConvertToText in a TextBlock but I can't find a way to use this function in a RichTextBlock!
From what I understand and tried I can't extend the RichTextBlock so I can't apply this function everytime a RichTextBlock is called.
Also, I can't find any way to bind text to a RichTextBlock and building a parser just for simple HTML (I only want paragraphs and italics/bolds) seems an overkill. Also, I have no idea where I should do this parsing since I the RichTextBlock seems unextendable.
I can't use the WebView because I need transparency (and from what I have read the WebView doesn't have it).
EDIT
@mydogisbox made me see I was getting too far on my research.
I can use HtmlUtilities.ConvertToText in the getter of a property that I can bind in the RichTextBlock. I couldn't bind it because I was trying to do
<Run Text="{Binding TextHTML}" /> without a <Paragraph> tag.
However HtmlUtilities.ConvertToText doesn't preserve italics or bolds. Only paragraphs :/.
I ended up using a package avaiable on gitHub that converts from HTML to a RickTextBlock.
Basiclly you only need to open the Package Manager Console (Tools > Library Package Manager > Package Manager Console) and install the package running Install-Package RichTextBlock.Html2Xaml.
Then you open RichTextBlockProperties.cs and you have the lines you need to copy. In my case I had to add the namespace:
xmlns:rtbx="using:EventTests.Common"
And then you can bind your property that has HTML using:
<RichTextBlock rtbx:Properties.Html="{Binding ...}"/>
Some problems and some solutions
A problem I have found with this library is how it handles simple html with no divs. Like:
<p>Testing <i>italic</i> and something more.</p>
<p>More testing </p>
This prints:
Testing italic and something more.
More testing
However, I wanted something like this:
Testing italic and something more.
More testing
So I had to wrap the second paragraph in a div (and all paragraphs except the first could be wrapped).
<p>Testing <i>italic</i> and something more.</p>
<div><p>More testing </p></div>
If you wrap the first paragraph then you will have an extra new line.
So far this is the best solution I have found. If you find better I apreciate it since I am testing and learning. If you find a better solution I will accept yours.
Be carefull
This approach will crash if you have symbols like "<" or "&" in your html. I suggest that you replace those chars before you try to use this library.
