and want get

<profile> <fullname>john doe</fullname> <otherdata>   <birthdate>1998</birthdate>   <favoritebooks>     <book>       <id>1</id>       <description>libre1book1</description>     </book>     <book>       <id>2</id>       <description>libre2book2</description>     </book>     <book>       <id>3</id>       <description>empty</description>     </book>     <book>       <id>4</id>       <description>libre4book4</description>     </book>     <book>       <id>5</id>       <description>new book5</description>     </book>   </favoritebooks> </otherdata>

i did pretty pathetic attempt, not work.

<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform"   xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl" > <xsl:output method="xml" indent="yes"/> <xsl:template match="/">   <profile>     <xsl:apply-templates select="combined/profile/fullname" />   </profile>   <otherdata>     <birthdate>       <xsl:apply-templates select="combined/loadeddata/newbirthdate"/>     </birthdate>     <favoritebooks>       <xsl:for-each select="/combined/profile/otherdata/favoritebooks/book">         <book>           <id>             <xsl:value-of select="id"/>           </id>           <description>             <xsl:value-of select="description"/>             <xsl:apply-templates select="/combined/loadeddata/booksupdate/book[@id='']" />           </description>         </book>       </xsl:for-each>     </favoritebooks>   </otherdata> </xsl:template> </xsl:stylesheet>

how can closer want get? advise me book jump start, because w3schools tutorials useless :(

how's this?

according logic described, description not "empty" rather "book3" (empty string merged "book3").

<!-- root , static content --> <xsl:template match="/">     <xsl:apply-templates select='combined/profile' /> </xsl:template>  <!-- identity/copy, tweaks --> <xsl:template match='node()|@*'>      <!-- copy node -->     <xsl:copy>          <!-- add in attributes -->         <xsl:apply-templates select='@*' />          <!-- either apply same treatment child nodes, or special -->         <xsl:choose>              <!-- use updated birthdate -->             <xsl:when test='name() = "birthdate"'>                 <xsl:value-of select='/combined/loadeddata/newbirthdate' />             </xsl:when>              <!-- merge book descriptions -->             <xsl:when test='name() = "description"'>                 <xsl:value-of select='concat(., /combined/loadeddata/booksupdate/book[@id = current()/../id]/booktext)' />             </xsl:when>              <!-- or keep recursing -->             <xsl:otherwise>                 <xsl:apply-templates select='node()' />             </xsl:otherwise>         </xsl:choose>     </xsl:copy>      <!-- if we've done books, add in in loaded data not original data -->     <xsl:if test='name() = "book" , not(count(following-sibling::book))'>         <xsl:variable name='orig_book_ids'>             <xsl:for-each select='../book'>                 <xsl:value-of select='concat("-",id,"-")' />             </xsl:for-each>         </xsl:variable>         <xsl:apply-templates select='/combined/loadeddata/booksupdate/book[not(contains($orig_book_ids, concat("-",@id,"-")))]' mode='new_books' />     </xsl:if> </xsl:template>  <!-- new books --> <xsl:template match='book' mode='new_books'>     <book>         <id><xsl:value-of select='@id' /></id>         <description>new <xsl:value-of select='booktext' /></description>     </book> </xsl:template>

you can run @ this xmlplayground session (see output source).

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
