Exploring XML Files in Search of Correlation Data

Specify the correlation in the tables

It seems that the file First assumption (Correlation).spv could not be read using the pyreadstat library, which is typically used for reading SPSS files.
Let's try another approach to read the file. We can attempt to read it as a binary file and inspect its contents to understand its structure better.
The file First assumption (Correlation).spv appears to be a ZIP archive containing XML files. This is indicated by the PK\x03\x04 signature at the beginning of the file, which is characteristic of ZIP files.
Let's extract the contents of the ZIP archive and inspect the XML files to understand the structure and locate the correlation data.
The ZIP archive has been successfully extracted. Here are the extracted files:
  • outputViewer0000000000.xml
  • 00000000011_lightNotesData.bin
  • 00000000012_lightTableData.bin
  • outputViewer0000000001_heading.xml
  • outputViewer0000000002.xml
  • 00000000031_lightTableData.bin
  • outputViewer0000000003_heading.xml
  • outputViewer0000000004.xml
  • 00000000051_lightNotesData.bin
  • 00000000052_lightTableData.bin
  • outputViewer0000000005_heading.xml
  • outputViewer0000000006.xml
  • 00000000071_lightNotesData.bin
  • 00000000072_-2481411033072140286_chartData.bin
  • 00000000072_-2481411033072140286_chart.xml
  • outputViewer0000000007_heading.xml
  • META-INF
Let's start by inspecting the XML files to locate the correlation data.
The root element of the first XML file (outputViewer0000000000.xml) is {http://xml.spss.com/spss/viewer/viewer-tree}heading, and it contains the following child elements:
  • {http://xml.spss.com/spss/viewer/viewer-tree}label
  • {http://xml.spss.com/spss/viewer/viewer-tree}container
Let's inspect the contents of these child elements to locate the correlation data.

Parse the second XML file

xml_file_path = './extracted_files/outputViewer0000000002.xml'
root = parse_xml(xml_file_path)

Print the root element and its children

[root.tag, [child.tag for child in root]]
The second XML file (outputViewer0000000002.xml) has a similar structure to the first one. The root element is {http://xml.spss.com/spss/viewer/viewer-tree}heading, and it contains the following child elements:
  • {http://xml.spss.com/spss/viewer/viewer-tree}label
  • {http://xml.spss.com/spss/viewer/viewer-tree}container
Let's inspect the contents of these child elements to locate the correlation data.
The second XML file contains the following relevant text:
EXAMINE VARIABLES=Score_Valed Ejtemaee_Score
  /PLOT STEMLEAF NPPLOT
  /STATISTICS DESCRIPTIVES
  /CINTERVAL 95
  /MISSING LISTWISE
  /NOTOTAL.
This indicates that the file contains some statistical analysis commands, but it does not seem to contain the correlation data directly.
Let's inspect the next XML file to continue our search for the correlation data.

Continue the analysis

The third XML file contains the following relevant text:
NONPAR CORR
  /VARIABLES=Score_Valed Ejtemaee_Score
  /PRINT=SPEARMAN TWOTAIL NOSIG
  /MISSING=PAIRWISE.
This indicates that the file contains commands for a non-parametric correlation analysis (Spearman correlation) between the variables Score_Valed and Ejtemaee_Score.
To locate the actual correlation data, we should inspect the remaining XML files and the .bin files, which might contain the results of the analysis.
The fourth XML file (outputViewer0000000006.xml) has a similar structure to the previous ones. The root element is {http://xml.spss.com/spss/viewer/viewer-tree}heading, and it contains the following child elements:
  • {http://xml.spss.com/spss/viewer/viewer-tree}label
  • {http://xml.spss.com/spss/viewer/viewer-tree}container
Let's inspect the contents of these child elements to locate the correlation data.
We have inspected the XML files and found that they contain commands for various statistical analyses, including descriptive statistics, non-parametric correlation (Spearman correlation), and scatterplot generation. However, the actual correlation data is not directly present in these XML files.
The next step is to inspect the .bin files, which might contain the results of the analyses. These files could contain the correlation data we are looking for.

بیشترین همبستگی ؟

برای یافتن بیشترین همبستگی، ابتدا باید داده‌های همبستگی را استخراج کنیم. از آنجا که داده‌های همبستگی به طور مستقیم در فایل‌های XML موجود نیستند، باید فایل‌های باینری (.bin) را بررسی کنیم.
بیایید ابتدا فایل‌های باینری را بررسی کنیم تا داده‌های همبستگی را استخراج کنیم.
We have identified several .bin files in the extracted_files directory. These files are:
  • 00000000011_lightNotesData.bin
  • 00000000012_lightTableData.bin
  • 00000000031_lightTableData.bin
  • 00000000051_lightNotesData.bin
  • 00000000052_lightTableData.bin
  • 00000000071_lightNotesData.bin
  • 00000000072_-2481411033072140286_chartData.bin
Next, we will inspect the contents of these files to locate the correlation data.
We have successfully extracted some data from the .bin files. However, the data appears to be a mix of valid and invalid values, which suggests that the binary format might be more complex than initially assumed.
To accurately decode the correlation data, we need to understand the specific binary format used by SPSS for storing correlation results. This might require additional information or documentation about the binary format.
Would you like to proceed with further analysis or provide additional information about the binary format?
