Regex Matching Words in XML Between Two Other Words (Matlab regexp) -

i'm trying parse xml file using matlab regexp. retrieve array of incidences of word "curvepoint" occuring between "deposits" , "/deposits". xml below should [6x1] array like

"

<curvepoint> <curvepoint> <curvepoint> <curvepoint> <curvepoint> <curvepoint> 

"

my attempt below doesn't work there lots of other text interspersed between each "curvepoint" word-incidence , look-aheads/backs, don't know how handle this.

regexp(xmltext,'(?<=<deposits>)(<curvepoint>)(?=</deposits>)','match')' 

xmltext is

<?xml version="1.0" encoding="utf-8"?> <interestratecurve>    <effectiveasof>2016-11-07</effectiveasof>    <currency>eur</currency>    <baddayconvention>m</baddayconvention>    <deposits>       <daycountconvention>act/360</daycountconvention>       <snaptime>2016-11-04t15:00:00.000z</snaptime>       <spotdate>2016-11-09</spotdate>       <calendars>          <calendar>none</calendar>       </calendars>       <curvepoint>          <tenor>1m</tenor>          <maturitydate>2016-12-09</maturitydate>          <parrate>-0.00373</parrate>       </curvepoint>       <curvepoint>          <tenor>2m</tenor>          <maturitydate>2017-01-09</maturitydate>          <parrate>-0.00339</parrate>       </curvepoint>       <curvepoint>          <tenor>3m</tenor>          <maturitydate>2017-02-09</maturitydate>          <parrate>-0.00312</parrate>       </curvepoint>       <curvepoint>          <tenor>6m</tenor>          <maturitydate>2017-05-09</maturitydate>          <parrate>-0.00213</parrate>       </curvepoint>       <curvepoint>          <tenor>9m</tenor>          <maturitydate>2017-08-09</maturitydate>          <parrate>-0.0013</parrate>       </curvepoint>       <curvepoint>          <tenor>1y</tenor>          <maturitydate>2017-11-09</maturitydate>          <parrate>-0.00071</parrate>       </curvepoint>    </deposits>    <swaps>       <fixeddaycountconvention>30/360</fixeddaycountconvention>       <floatingdaycountconvention>act/360</floatingdaycountconvention>       <fixedpaymentfrequency>1y</fixedpaymentfrequency>       <floatingpaymentfrequency>6m</floatingpaymentfrequency>       <snaptime>2016-11-04t15:00:00.000z</snaptime>       <spotdate>2016-11-09</spotdate>       <calendars>          <calendar>none</calendar>       </calendars>       <curvepoint>          <tenor>2y</tenor>          <maturitydate>2018-11-09</maturitydate>          <parrate>-0.00157</parrate>       </curvepoint>       <curvepoint>          <tenor>3y</tenor>          <maturitydate>2019-11-09</maturitydate>          <parrate>-0.00115</parrate>       </curvepoint>       <curvepoint>          <tenor>4y</tenor>          <maturitydate>2020-11-09</maturitydate>          <parrate>-0.00059</parrate>       </curvepoint>       <curvepoint>          <tenor>5y</tenor>          <maturitydate>2021-11-09</maturitydate>          <parrate>0.00017</parrate>       </curvepoint>       <curvepoint>          <tenor>6y</tenor>          <maturitydate>2022-11-09</maturitydate>          <parrate>0.00108</parrate>       </curvepoint>       <curvepoint>          <tenor>7y</tenor>          <maturitydate>2023-11-09</maturitydate>          <parrate>0.0021</parrate>       </curvepoint>       <curvepoint>          <tenor>8y</tenor>          <maturitydate>2024-11-09</maturitydate>          <parrate>0.00316</parrate>       </curvepoint>       <curvepoint>          <tenor>9y</tenor>          <maturitydate>2025-11-09</maturitydate>          <parrate>0.00419</parrate>       </curvepoint>       <curvepoint>          <tenor>10y</tenor>          <maturitydate>2026-11-09</maturitydate>          <parrate>0.00513</parrate>       </curvepoint>       <curvepoint>          <tenor>12y</tenor>          <maturitydate>2028-11-09</maturitydate>          <parrate>0.00673</parrate>       </curvepoint>       <curvepoint>          <tenor>15y</tenor>          <maturitydate>2031-11-09</maturitydate>          <parrate>0.00838</parrate>       </curvepoint>       <curvepoint>          <tenor>20y</tenor>          <maturitydate>2036-11-09</maturitydate>          <parrate>0.00966</parrate>       </curvepoint>       <curvepoint>          <tenor>30y</tenor>          <maturitydate>2046-11-09</maturitydate>          <parrate>0.01006</parrate>       </curvepoint>    </swaps> </interestratecurve> 

never use regex parse xml. @ best solution brittle. use real xml parser instead.

in matlab, use xmlread, xmlwrite, , xslt functions read, write, , transform xml.

note mathworks blog has xml posts on using these functions in matlab.
