Question

我已使用SharpVector将SVG图像转换为XAML，后者创建了以下代码：

File "/home/openerp/clean_oe7/server/openerp/report/report_sxw.py", line 442, in create
    pdf = create_doc(etree.tostring(processed_rml),rml_parser.localcontext,logo,title.encode('utf8'))
  File "/home/openerp/clean_oe7/server/openerp/report/interface.py", line 206, in create_pdf
    obj.render()
  File "/home/openerp/clean_oe7/server/openerp/report/render/render.py", line 59, in render
    self._result = self._render()
  File "/home/openerp/clean_oe7/server/openerp/report/render/rml.py", line 41, in _render
    return rml2pdf.parseNode(self.rml, self.localcontext, images=self.bin_datas, path=self.path,title=self.title)
  File "/home/openerp/clean_oe7/server/openerp/report/render/rml2pdf/trml2pdf.py", line 1032, in parseNode
    r.render(fp)
  File "/home/openerp/clean_oe7/server/openerp/report/render/rml2pdf/trml2pdf.py", line 328, in render
    pt_obj.render(el)
  File "/home/openerp/clean_oe7/server/openerp/report/render/rml2pdf/trml2pdf.py", line 1003, in render
    fis += r.render(node_story)
  File "/home/openerp/clean_oe7/server/openerp/report/render/rml2pdf/trml2pdf.py", line 897, in render
        return process_story(node_story)
  File "/home/openerp/clean_oe7/server/openerp/report/render/rml2pdf/trml2pdf.py", line 890, in process_story
    flow = self._flowable(node)
  File "/home/openerp/clean_oe7/server/openerp/report/render/rml2pdf/trml2pdf.py", line 813, in _flowable
    return  self._table(node)
  File "/home/openerp/clean_oe7/server/openerp/report/render/rml2pdf/trml2pdf.py", line 697, in _table
    fl = self._flowable(n, extra_style=paraStyle)
  File "/home/openerp/clean_oe7/server/openerp/report/render/rml2pdf/trml2pdf.py", line 766, in _flowable
    result.append(platypus.Paragraph(i, style, **(utils.attr_get(node, [], {'bulletText':'str'}))))
  File "/usr/lib/python2.7/dist-packages/reportlab/platypus/paragraph.py", line 827, in __init__
    self._setup(text, style, bulletText, frags, cleanBlockQuotedText)
  File "/usr/lib/python2.7/dist-packages/reportlab/platypus/paragraph.py", line 842, in _setup
    style, frags, bulletTextFrags = _parser.parse(text,style)
  File "/usr/lib/python2.7/dist-packages/reportlab/platypus/paraparser.py", line 1057, in parse
    self.close()    # force parsing to complete
  File "/usr/lib/python2.7/dist-packages/reportlab/lib/xmllib.py", line 521, in close
    self.parser.close()
AttributeError: 'NoneType' object has no attribute 'close'

我想要的是搜索属性值为x：Name =“paths”的DrawingGroup标签，然后在<DrawingGroup> <DrawingGroup x:Name="DrawingLayer"> <DrawingGroup x:Name="Rooms"> <Drawing Group> .. </DrawingGroup> .. .. </DrawingGroup> <DrawingGroup x:Name="Paths"> <GeometryDrawing> <GeometryDrawing.Pen> <Pen Brush="#FF0000FF" Thickness="1"StartLineCap="Flat"EndLineCap="Flat" LineJoin="Miter" opacity="1" /> </GeometryDrawing.Pen> <GeometryDrawing.Geometry> <LineGeometry StartPoint="378,45" EndPoint="378,98" /> </GeometryDrawing.Geometry> </GeometryDrawing> <GeometryDrawing> ..</GeometryDrawing> </GeometryDrawing> .. </GeometryDrawing> </DrawingGroup>中进行更改我在加载时加载此xaml文件。我完全对这个文件感到困惑..

你可以在元素本身上放一个x：Name，不需要搜索DrawingGroup x：Name

<Pen Brush="#FF0000FF" Thickness="1" StartLineCap="Flat" EndLineCap="Flat" LineJoin="Miter" x:Name="Pen1"/>

并从CodeBehind编辑它：

Pen1.Thickness = 100;

编辑：因为你在运行时获得了XAML：

 ((GeometryDrawing)Paths.Children[0]).Pen.Thickness = 100;
