xml - How to remove and add select elements via XSLT? -

-

i have following xml document (just excerpt):

<osm>   <node id="1" version="1" timestamp="2016-02-29t01:33:20z" lat="0.0" lon="0.657002">     <tag k="stat_nr" v="40045"/>     <tag k="ortsgr_kl" v="0"/>     <tag k="town_id" v="0000"/>     <tag k="name2" v="city2"/>     <tag k="name1" v="city1"/>     <tag k="id" v="8942835"/>   </node>   <node id="2" version="1" timestamp="2016-02-29t01:33:20z" lat="0.93198" lon="0.000">     <tag k="land" v="d"/>     <tag k="id_ref" v=""/>     <tag k="stat_nr" v="40045"/>     <tag k="name1" v="examplecity"/>     <tag k="id" v="0000"/>   </node> </osm>

what following result:

<osm>   <node id="1" version="1" timestamp="2016-02-29t01:33:20z" lat="0.0" lon="0.657002">     <tag k="stat_nr" v="40045"/>     <tag k="name1" v="city1"/>     <tag k="id" v="8942835"/>     <tag k="test" v="8942835"/>   </node>   <node id="2" version="1" timestamp="2016-02-29t01:33:20z" lat="0.93198" lon="0.000">     <tag k="stat_nr" v="40045"/>     <tag k="name1" v="examplecity"/>     <tag k="id" v="0000"/>     <tag k="test" v="0000"/>   </node> </osm>

delete except each of following tags:

<tag k="stat_nr"> <tag k="name1"  > <tag k="id" >

but add new tag copying values k="id" v=:

<tag k="test" v="8942835"/> <tag k="test" v="0000"/>

given xml, repaired well-formed using same case on closing osm tag opening osm tag,

<osm>   <node id="1" version="1" timestamp="2016-02-29t01:33:20z" lat="0.0" lon="0.657002">     <tag k="stat_nr" v="40045"/>     <tag k="ortsgr_kl" v="0"/>     <tag k="town_id" v="0000"/>     <tag k="name2" v="city2"/>     <tag k="name1" v="city1"/>     <tag k="id" v="8942835"/>   </node>   <node id="2" version="1" timestamp="2016-02-29t01:33:20z" lat="0.93198" lon="0.000">     <tag k="land" v="d"/>     <tag k="id_ref" v=""/>     <tag k="stat_nr" v="40045"/>     <tag k="name1" v="examplecity"/>     <tag k="id" v="0000"/>   </node> </osm>

this xslt, based on identity transformation 1 template added squelch requested tag elements , 1 template added append requested tag elements,

<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform">   <xsl:output method="xml" indent="yes"/>   <xsl:strip-space elements="*"/>    <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>    <xsl:template match="tag[@k!='stat_nr' , @k!='name1' , @k!='id']"/>    <xsl:template match="tag[@k='id']">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>     <tag k="test" value="{@v}"/>   </xsl:template>  </xsl:stylesheet>

will produce xml,

<?xml version="1.0" encoding="utf-8"?> <osm>    <node id="1"          version="1"          timestamp="2016-02-29t01:33:20z"          lat="0.0"          lon="0.657002">       <tag k="stat_nr" v="40045"/>       <tag k="name1" v="city1"/>       <tag k="id" v="8942835"/>       <tag k="test" value="8942835"/>    </node>    <node id="2"          version="1"          timestamp="2016-02-29t01:33:20z"          lat="0.93198"          lon="0.000">       <tag k="stat_nr" v="40045"/>       <tag k="name1" v="examplecity"/>       <tag k="id" v="0000"/>       <tag k="test" value="0000"/>    </node> </osm>

as requested.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
