使用Node.js中的XSLT字符串将XML字符串[不是文件!]转换为HTML [英] Transform XML String [not file!] with XSLT String in Node.js to HTML
问题描述
我有两个字符串。
第一个是xml字符串,另存为字符串,而不是文件中。
第二个是我使用 fs.readFile(...)
从XSLT文件加载的字符串。
The first one is a xml string, saved as a string, not from a file.
The second one is a string I load from a XSLT file with fs.readFile(...)
.
我已经尝试使用 libxslt
,但是由于与MSBuildTools和MSBuildTools有关的某些错误而无法通过 npm
安装它
I already tried using libxslt
but can't install it via npm
due to some errors about MSBuildTools and so on.
libxslt
是否有其他选择?我已经遇到过 xslt处理器
了,但是它只接受文件作为参数。
Are there any alternatives for libxslt
? I already came across xslt-processor
too, but it only accepts files as parameters.
编辑1:
为了向您提供概述,可以在此处下载XSLT文件和示例XML文件(均在应用程序中作为字符串处理):
to provide you an overview, the XSLT file and an example XML file (both handled as strings in the app) can be downloaded here:
- Stylesheet in a ZIP File
- Example XML Files in a ZIP
推荐答案
我以某种方式解决了我的问题:
I somehow got a workaround for my problem:
- 我现在使用
xth
库(通过npm安装:npm i xth
) - 将其导入到我的函数中:
var xth = require('xth');
- 将xml字符串放入数据URI:
var xml ='data:text / xml'+ encodeURICompon ent(xmlString);
- XSLT文件现在不是字符串,而是文件:
var xsl ='./../ components / ELGA_Stylesheet_v1-0.xsl';
-
然后,我就像在 xth-npm
- I now use the
xth
library (install via npm:npm i xth
) - import it into my function:
var xth = require('xth');
- put the xml String into a data URI:
var xml = 'data:text/xml,' + encodeURIComponent(xmlString);
- the XSLT file is now not a String but the file:
var xsl = './../components/ELGA_Stylesheet_v1-0.xsl';
Then, I just call the method xth as in the example at xth - npm
1 xth( xml,xsl,函数(html){
2 html = html.replace(/& lt // g,<);
3 html = html.replace(/& / g,>);
4 html = html.replace(/& / g,&);
5 openWindow(html);
6});
项目 html
是在使用xslt转换的字符串时,我遇到了最后一个问题:在输出字符串的< script>
标记中,符号<,>和&以&lt ;、&gt;和&amp;造成了问题。第2至4行是此问题的解决方法
the item html
is the xslt transformed string, I had one final problem: in the <script>
Tags of the output string, the symbols <,> and & were there as &lt;, &gt;, and &amp; which caused problems. lines 2 to 4 are the workaround for this issue
openWindow(html)
是我自己的方法,可以在新的电子窗口中打开结果字符串。
openWindow(html)
is my own method to open the result string in a new electron window.
注意:一个问题仍然存在:如前所述在此处,通过< a href =#id>
中的#导航无效,因为Chromium不允许导航到数据uri的顶部框架。
NOTE: one problem remains: as mentioned here, navigation via # in <a href=#id>
doesn't work, because Chromium doesn't allow navigation to top frame to data uri.
