xml - XSL string parsing and getting value with a bid oddity -


been fighting xml beginner, , result have have work with. xml being returned following:

<response .... />   <metric ... />      <stuff .... />      <stuff  .... sname="on"  tag="parameters: (@sid: dftdr.23423.s1.rt, @stype: x)" />

well trying output select parameters , sid value there. display in example, parameters dtfdr.23423.s1.rt . got 1 half of done doing this:

<xsl:value-of select="substring(/response/metric/stuff[@sname='on'][1]/@tag, 1, 9)"/>

but can't think of way parse sid out dynamic value getting length. can start position can't seem figure out , easy indexof concept "," or if there's better way this.

this base xml it's cards dealt, can't change it.

is there easier way write out buried @sid value?

much help, hope explained enough.

try expression parse out sid

<xsl:value-of select="substring-before(substring-after(/response/metric/stuff[@sname='on'][1]/@tag, '@sid: '), ',')"/>

datatable - Matlab struct computations -

i download data yahoo! finance with: data = getyahoodailydata({'msft', 'axp'},'01/01/2000', '01/01/2015', 'dd/mm/yyyy'); and data stored 1x1 struct. want create tx2 matrix of daily adjusted closing prices msft , axp, column 7 in each table in struct. how can that? or better : there way make computations directly on information/prices in struct? you can access data in struct name. vecmsftadj = data.msft.adjclose; vecaxpadj = data.axp.adjclose; % if want n x 2 matrix madjclose = [vecmsftadj, vecaxpadj]; % personnaly prefer working table tadjclose = table; tadjclose.msftadj = vecmsftadj; tadjclose.axpadj = vecaxpadj;
