Hi I have an mpd which has the following information

<BaseURL>01/</BaseURL>
                                <SegmentList timescale="1000">

I want to grep for base url/01 what are all the segment urls and for base url/02 what are all the segment urls can you please help as I am new to scripting...

The desired output I am looking for is for base url/01 saved into a different file and the same for base url/02

<BaseURL>01/</BaseURL>
<SegmentURL media="1.ts" mediaRange="0-3424419"/>
                                        <SegmentURL media="2.ts" mediaRange="0-8063319"/>
                                        <SegmentURL media="3.ts" mediaRange="0-7146631"/>
                                        <SegmentURL media="4.ts" mediaRange="0-8984143"/>
                                        <SegmentURL media="5.ts" mediaRange="0-7496499"/>
                                        <SegmentURL media="6.ts" mediaRange="0-10445091"/>
                                        <SegmentURL media="7.ts" mediaRange="0-8854423"/>

I suggest you the use of xml2 (http://www.ofb.net/~egnor/xml2/) to transform the xml to something grep-able.

Unfortunately the xml you posted seems broken to me, please update the question.
