<div>Hi :</div>
<div>I want to handle some hdf4 data using gdal,and my goal is to get the subdatasetname of one hdf4,and I know I can use the gdalinfo to get the information,however what I get is just some plain text format as follows:</div>

<div>-------------------------------------------------------------------------------</div>
<div>So if I want to extract the subdataset name I should parser the text by myself,</div>
<div>I wonder if there are some liberary can do it using its method(maybe like this [getSubDataSetArrry()]).</div>
<div> </div>
<div>BTW,I am using java,and I want to know how to install the gdal in the xp os? Since I am using the gdal included in FWTools2.2.8,so I have to install the FWTTools frist,I wonder if there is other easy way?</div></div>
