<?summary-of-invention description="Summary of Invention" end="lead"?>
<heading id="h-0001" level="1">BACKGROUND OF THE INVENTION</heading>
<heading id="h-0002" level="1">1) Field of the Invention</heading>
<p id="p-0002" num="0001">The present invention relates to a vehicle roof-mounted shading apparatus, capable of both vertical and horizontal movement, to shade a vehicle from the sun.</p>
<heading id="h-0003" level="1">2) Description of Related Art</heading>
<p id="p-0003" num="0002">The interior of a car parked outdoors on a hot sunny day can reach very high temperatures in a short period of time. This drastic temperature increase is caused by a combination of hot temperatures outside the car and lack of proper ventilation for the hot air to escape from within and surrounding the exterior of the car. Ultraviolet radiation from the sun also enters through the windshields and windows and heats the air in the car. The front windshield may also act like a magnifying glass, intensifying sun rays.</p>
<p id="p-0004" num="0003">These extreme conditions not only cause discomfort to the driver and passengers upon re-entering, but may also damage the interior of the car. Two methods that are normally used to reduce temperature build-up in a vehicle are tinting the windows or using sunshades. Tinting the window involves permanently installing a film on the window of the car. In some countries, this is not permitted by law.</p>
<p id="p-0005" num="0004">There have been a number of efforts to cover parked cars and protect them from very high internal temperatures caused by the sun's rays. To date, these efforts all have had designs that make them best suited for long term parking because of the difficulties one would have in using the various systems. Most sit on the car surface, which is not good for the vehicle's finish and traps heat at the vehicle exterior.</p>
<p id="p-0006" num="0005">Several efforts have tried to address all problems that could occur, such as rain, snow, hail, sleet, and wind as well as sun rays. Some devices have to be removed and stored in the trunk to operate the car. Other applications have to be wired into the car's electrical system or have parts welded onto the car roof or trunk or would need several people to deploy the device for use. For instance, Patel, U.S. Pat. No. 8,308,217, provides a sun shade for interior use of a vehicle. The shade includes a scissors type extension mechanism but lacks internally supported tubing and is incapable of both vertical and horizontal movement with respect to a vehicle.</p>
<p id="p-0082" num="0081">While the present subject matter has been described in detail with respect to specific exemplary embodiments and methods thereof, it will be appreciated that those skilled in the art, upon attaining an understanding of the foregoing may readily produce alterations to, variations of, and equivalents to such embodiments. Accordingly, the scope of the present disclosure is by way of example rather than by way of limitation, and the subject disclosure does not preclude inclusion of such modifications, variations and/or additions to the present subject matter as would be readily apparent to one of ordinary skill in the art using the teachings disclosed herein.</p>

And here is my code following the first answer to the above mentioned question.
import pandas as pd
import xml.etree.ElementTree as ET
def iter_docs(author):
author_attr = author.attrib
#print(author.attrib)
for doc in author.iter():
doc_dict = author_attr.copy()
doc_dict.update(doc.attrib)
doc_dict['data'] = doc.text
print(doc_dict)
yield doc_dict
etree = ET.parse("1.xml") #create an ElementTree object
doc_df = pd.DataFrame(list(iter_docs(etree.getroot())))
print(doc_df.head())
However most of the columns of the data frame are NaN, not to mention that there should be only one row. I think this is because this file has a more complicated format than the one in the referred question. How should I modify the Python code?
