Docx Dual Parse

Before extraction, detect which method will work:

# Quick shell method test
if unzip -v >/dev/null 2>&1; then
    echo "Shell method available"
else
    echo "Shell method unavailable, try Python"
fi

# Quick Python method test
python3 -c "import zipfile; print('Python method available')" 2>/dev/null

Method A: Shell-Based Extraction

Use when unzip and sed are available and the environment allows shell operations.

Step-by-Step Instructions

1. Verify the DOCX file exists

ls -la document.docx

2. Extract raw XML content

unzip -p document.docx word/document.xml

3. Strip XML tags from content

unzip -p document.docx word/document.xml | sed -e 's/<[^>]*>//g'

4. Clean up whitespace (optional)

unzip -p document.docx word/document.xml | \
  sed -e 's/<[^>]*>//g' | \
  sed -e 's/^[[:space:]]*//' -e 's/[[:space:]]*$//' | \
  sed -e '/^$/d'

5. Save extracted text to file

unzip -p document.docx word/document.xml | \
  sed -e 's/<[^>]*>//g' > output.txt

Reusable Shell Function

parse_docx_shell() {
    local file="$1"
    if [ ! -f "$file" ]; then
        echo "Error: File not found: $file" >&2
        return 1
    fi
    if ! command -v unzip >/dev/null 2>&1; then
        echo "Error: unzip not available" >&2
        return 1
    fi
    unzip -p "$file" word/document.xml 2>/dev/null | \
        sed -e 's/<[^>]*>//g' | \
        sed -e 's/^[[:space:]]*//' -e 's/[[:space:]]*$//' | \
        sed -e '/^$/d'
}

# Usage: parse_docx_shell document.docx

Method B: Python Zipfile Extraction

Use when shell method fails or Python environment is more reliable than shell.

Step-by-Step Instructions

1. Verify the DOCX file exists

ls -la document.docx

2. Run Python extraction via run_shell

run_shell 'python3 -c "
import zipfile
import re
with zipfile.ZipFile(\"document.docx\", \"r\") as z:
    content = z.read(\"word/document.xml\").decode(\"utf-8\")
    text = re.sub(r\"<[^>]*>\", \"\", content)
    lines = [l.strip() for l in text.splitlines() if l.strip()]
    for line in lines:
        print(line)
"'

3. Save to file by redirecting output

run_shell 'python3 -c "
import zipfile
import re
with zipfile.ZipFile(\"document.docx\", \"r\") as z:
    content = z.read(\"word/document.xml\").decode(\"utf-8\")
    text = re.sub(r\"<[^>]*>\", \"\", content)
    lines = [l.strip() for l in text.splitlines() if l.strip()]
    with open(\"output.txt\", \"w\") as f:
        for line in lines:
            f.write(line + \"\\n\")
"'

Reusable Python Function (via run_shell)

parse_docx_python() {
    local file="$1"
    local output="$2"
    if [ ! -f "$file" ]; then
        echo "Error: File not found: $file" >&2
        return 1
    fi
    run_shell "python3 -c \"
import zipfile
import re
import sys
