从“伪”HTML中提取文本

Question

我正在尝试将生产执行系统（MES）SQL数据库中的工单重新生成为.pdf格式，以便可以整体打印，而不是一次打印一份（MES只允许一份）

当涉及到包含链接等（伪html…不知道还能叫它什么）的工作说明时，我被卡住了。我对所需的数据运行SQL查询，并将其放入数据框中。以下是数据框中“文本”列（工作说明）的示例：

"DWG/TECH DATA: ALL TASK WITHIN THIS WORK ORDER ARE TO BE ACCOMPLISHED IAW: <#Tab><UT=""LinkInvoke(Slide(OBJECT_ID=OBJECTID,@GlyphName=@InlineText,@Classification=General,@RenderDescText=True,'@Desc=| Description: PANEL, |',@Caption=DWG 123456-123 ,REF_ID=REFID))""><#Tab> MOA DWG: <#Tab><UT=""LinkInvoke(Slide(OBJECT_ID=OBJECT ID,@GlyphName=@InlineText,@Classification=General,@RenderDescText=True,'@Desc=| Description: FACEPLATES |',@Caption=DWG 98765 Plate,REF_ID=REFID))""> <#Tab><UT=""LinkInvoke(Slide(OBJECT_ID=OBJID,@GlyphName=@InlineText,@Classification=General,@RenderDescText=True,'@Desc=| Description: ARTWORK |',@Caption=DWG 9999-8888 ARTWORK ,REF_ID=REFID))""><#Tab>"

Answer 1

通过字符串操作（而不是正则表达式），可以使用以下方法：

work = '''DWG/TECH DATA: ALL TASK WITHIN THIS WORK ORDER ARE TO BE ACCOMPLISHED IAW:
<#Tab><UT=""LinkInvoke(Slide(OBJECT_ID=OBJECTID,@GlyphName=@InlineText,@Classification=General,@RenderDescText=True,'@Desc=| Description: PANEL, |',@Caption=DWG 123456-123 ,REF_ID=REFID))""><#Tab>
MOA DWG:
<#Tab><UT=""LinkInvoke(Slide(OBJECT_ID=OBJECT ID,@GlyphName=@InlineText,@Classification=General,@RenderDescText=True,'@Desc=| Description: FACEPLATES |',@Caption=DWG 98765 Plate,REF_ID=REFID))"">
<#Tab><UT=""LinkInvoke(Slide(OBJECT_ID=OBJID,@GlyphName=@InlineText,@Classification=General,@RenderDescText=True,'@Desc=| Description: ARTWORK |',@Caption=DWG 9999-8888 ARTWORK ,REF_ID=REFID))""><#Tab>"
'''

work_dat = work.splitlines()
for line in work_dat:
    line_lst = line.split('|')
    step_1 = [item  if "@Caption=" in item else line_lst for item in line_lst][0]
    step_2 = [item if len(step_1)==1 else step_1[2] for item in step_1]
    if len(step_2)>1:
        print(step_2[1].split('=')[1].split(',')[0].strip())
    else:
        print(step_2[0])

输出：

DWG/TECH DATA: ALL TASK WITHIN THIS WORK ORDER ARE TO BE ACCOMPLISHED IAW:
DWG 123456-123
MOA DWG:
DWG 98765 Plate
DWG 9999-8888 ARTWORK
