下载得到文件：
pdfminer-20100322.tar.gz

uppack it. Run setup.py to install:
E:\tools\python\pdfminer\pdfminer-20100322>python setup.py install

try the pdf2txt.py comand:
E:\tools\python\pdfminer\pdfminer-20100322>pdf2txt.py samples/simple1.pdf
Hello

解析得到了这个PDF的内容，证明我们安装成功了。

测试解析我需要解析的pdf内容：
解析保存为txt
pdf2txt.py -o "01-27 Mar 10.txt" "01-27 Mar 10.pdf"
解析保存为xml
pdf2txt.py -t xml -o "01-27 Mar 10.xml" "01-27 Mar 10.pdf"
解析保存为html
pdf2txt.py -t html -o "01-27 Mar 10.html" "01-27 Mar 10.pdf"

其中比较适合我使用的是txt，我将pdf中的文字内容解析为txt后，读取里面的信息。

参考c:\Python26\Scripts\pdf2txt.py的代码，写了个测试pdfTest.py来从pdf得到txt:
