i using javax.xml.parsers.documentbuilder parse existing xml file , instance of org.w3c.dom.document . after manipulations on instance, need write file. therefore how can write org.w3c.dom.document object xml file using xmlstreamwriter ? ps: asking this, because think need use xmlstreamwriter in order write xml file without losing attribute orders. attribute orders important because in version tree, because of attribute order changes, don't want see xml file changed. attribute order insignificant per xml recommendation : note order of attribute specifications in start-tag or empty-element tag not significant. therefore, xmlstreamwriter provides no way constrain attribute ordering. in general, xml recommendations consider attribute ordering insignificant, see section on attribute processing in xml normalization recommendation or canonical xml recommendation if application has need attribute ordering.

i'm wondering if it's possible add little maths sorting database mysql , php. in short, friend wanting website people pay want service, attention go higher payments, , work down lower ones when has time. the easy way order records amount paid, mean payment of 5p priority on that's been sitting there 20 days, had idea of incrementing amount paid 1p per day. is there way sql statement doesn't involve writing table, or should php array , calculations there? alternatively worth having 2 tables in database, 1 incremented cost, , other keep track of when last updated, avoid having recalculate more once day? i'd try have efficient solution, , while php calculation route seems easiest, i'd have process records @ once , sort them, might quite heavy on server. you can using datediff() : order payment + datediff(curdate(), submitdate) desc
