如何在Python中将一些变量值传递给RML文件？

给定一个用于在 python 中生成 PDF 文件的 RML 模板，如何在 RML 模板文件中使用 Python 脚本中声明的变量？

def create_pdf:
   name = "My Name"

   with open('/file.rml') as rml:
         data = rml.read()
   pdf = rml2pdf.parseString(data)
   with open(f"/newpdf.pdf", 'wb') as output:
         output.write(pdf.read())
   return HttpResponse(status=200)

这是模板file.rml：

<?xml version="1.0" encoding="utf-8" standalone="no" ?> 
<!DOCTYPE document SYSTEM "rml_1_0.dtd">
<document filename="file.rml">
   .....
    <story>
        <para style="h1-center">[[name]]</para> <!-- Name value should appear here -->
    </story>
</document>

那么如何获取模板中的name变量值呢？

Given an RML template, used to generate PDF file in python, how can one use variables declared in a Python script in the RML template file?

def create_pdf:
   name = "My Name"

   with open('/file.rml') as rml:
         data = rml.read()
   pdf = rml2pdf.parseString(data)
   with open(f"/newpdf.pdf", 'wb') as output:
         output.write(pdf.read())
   return HttpResponse(status=200)

Here is the template file.rml:

<?xml version="1.0" encoding="utf-8" standalone="no" ?> 
<!DOCTYPE document SYSTEM "rml_1_0.dtd">
<document filename="file.rml">
   .....
    <story>
        <para style="h1-center">[[name]]</para> <!-- Name value should appear here -->
    </story>
</document>

So how do I get the name variable value in the template?

您可以使用 genshi 预处理您的文件：

<?xml version="1.0" encoding="utf-8" standalone="no" ?> 
<!DOCTYPE document SYSTEM "rml_1_0.dtd">
<document xmlns:py="http://genshi.edgewall.org/" filename="file.rml">
   .....
    <story>
        <para style="h1-center" py:content="name" /> <!-- Name value should appear here -->
    </story>
</document>

Genshi template > RML文件> PDF

You may preprocess your file with genshi:

<?xml version="1.0" encoding="utf-8" standalone="no" ?> 
<!DOCTYPE document SYSTEM "rml_1_0.dtd">
<document xmlns:py="http://genshi.edgewall.org/" filename="file.rml">
   .....
    <story>
        <para style="h1-center" py:content="name" /> <!-- Name value should appear here -->
    </story>
</document>

Genshi template > RML file > PDF
