关于利用trml2pdf生成PDF出现【flowable not yet implemented】错误的原因

最近一直在研究利用RML制作PDF，中间一直遇到各种flowable not yet implemented的错误，郁闷球坏了，今天在去trml2pdf.py源码中查看，发现trml2pdf.py对很对RML标签并没有解析：

def _flowable(self, node):if node.localName=='para':style = self.styles.para_style_get(node)return platypus.Paragraph(self._textual(node), style, **(utils.attr_get(node, [], {'bulletText':'str'})))elif node.localName=='name':self.styles.names[ node.getAttribute('id')] = node.getAttribute('value')return Noneelif node.localName=='xpre':style = self.styles.para_style_get(node)return platypus.XPreformatted(self._textual(node), style, **(utils.attr_get(node, [], {'bulletText':'str','dedent':'int','frags':'int'})))elif node.localName=='pre':style = self.styles.para_style_get(node)return platypus.Preformatted(self._textual(node), style, **(utils.attr_get(node, [], {'bulletText':'str','dedent':'int'})))elif node.localName=='illustration':return  self._illustration(node)elif node.localName=='blockTable':return  self._table(node)elif node.localName=='title':styles = reportlab.lib.styles.getSampleStyleSheet()style = styles['Title']return platypus.Paragraph(self._textual(node), style, **(utils.attr_get(node, [], {'bulletText':'str'})))elif node.localName=='h1':styles = reportlab.lib.styles.getSampleStyleSheet()style = styles['Heading1']return platypus.Paragraph(self._textual(node), style, **(utils.attr_get(node, [], {'bulletText':'str'})))elif node.localName=='h2':styles = reportlab.lib.styles.getSampleStyleSheet()style = styles['Heading2']return platypus.Paragraph(self._textual(node), style, **(utils.attr_get(node, [], {'bulletText':'str'})))elif node.localName=='h3':styles = reportlab.lib.styles.getSampleStyleSheet()style = styles['Heading3']return platypus.Paragraph(self._textual(node), style, **(utils.attr_get(node, [], {'bulletText':'str'})))elif node.localName=='image':return platypus.Image(node.getAttribute('file'), mask=(250,255,250,255,250,255), **(utils.attr_get(node, ['width','height'])))elif node.localName=='spacer':if node.hasAttribute('width'):width = utils.unit_get(node.getAttribute('width'))else:width = utils.unit_get('1cm')length = utils.unit_get(node.getAttribute('length'))return platypus.Spacer(width=width, height=length)elif node.localName=='pageBreak':return platypus.PageBreak()elif node.localName=='condPageBreak':return platypus.CondPageBreak(**(utils.attr_get(node, ['height'])))elif node.localName=='setNextTemplate':return platypus.NextPageTemplate(str(node.getAttribute('name')))elif node.localName=='nextFrame':return platypus.CondPageBreak(1000)           # TODO: change the 1000 !else:sys.stderr.write('Warning: flowable not yet implemented: %s !\n' % (node.localName,))return None

在这段代码中查找<nextPage/>、<outlineAdd>、<storePlace>......这些标签都没有，

现在解决的方法就是，换用reportlab api直接写或者修改trml2pdf.py的源码来解析无法识别的一些标签

好吧，我现在也不纠结了，如果哪位大神有比较全面的rml转pdf的工具，希望传给小弟一份邮箱:513614549@qq.com
