xml - xslt: contextless 'generate-id'? -

-

as understand it, xslt function generate-id() return unique id depending on node , context (ancestors).

is there way obtain id dependent on node (and subnodes), , not position in document?

when using xinclude, identical nodes can put multiple locations -- , hence have 2 different ids generated. how can create alphanumeric string identical each instance of node-set inserted document via xinclude?

so have file node.xml:

<?xml version="1.0" encoding="utf-8"?> <node name="joe"/>

and document.xml:

<?xml version="1.0" encoding="utf-8"?> <document xmlns:xi="http://www.w3.org/2003/xinclude">     <container name="first">         <xi:include href="node.xml"/>     </container>     <container name="second">         <xi:include href="node.xml"/>     </container> </document>

and process.xslt:

<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform"> <xsl:template match="container"> not identical different matches of template, although matched <node/> has same content: '<xsl:value-of select="generate-id(node)"/>' appending attributes simple, there might differences deeper down hierarchy, should resolve in different id: '<xsl:value-of select="node/@name"/>' </xsl:template> </xsl:stylesheet>

process xsltproc --xinclude process.xslt document.xml. need same id/string both occurrences of <node/>, identical.

greetings

argh. this looks remarkably similar. however, not want manually concat values...? not scale in case... maybe can work out using number() feels there should more auto...

ps: using xsltproc, no fancy-pancy... ;-)

the 2 node elements not identical. have same children/attributes/descendants, have different parents , different siblings.

the 2 node elements deep-equal according xpath 2.0 definition of deep-equal function. deep-equal spec no means possible way function specified: read spec , see number of rules have been defined differently. (e.g. dependencies on namespace prefixes, whitespace-only text nodes, in-scope namespaces, base uri, type annotations).

given caveats, there cases useful have function fingerprint(node) such fingerprint(n) = fingerprint(m) if , if deep-equal(n, m). write own function not @ easy write, , might not efficient.

so know why think need it, because there may easier way solve problem.

Formatting string according to pattern without regex in php -

how can format arbitrary string according flexible pattern? solution came using regular expressions, need 2 "patterns" (one search , 1 output). example: $str = '123abc5678"; desired output: 12.3ab-c5-67.8 i use pattern in variable (one user can define without knowledge of regular expressions) this: $pattern = '%%.%%%-%%-%%.%'; so user have use 2 different characters (% , .) a solution regex this: $str = '123abc5678'; $pattern_src = '@(.{2})(.{3})(.{2})(.{2})(.{1})@'; $pattern_rpl = "$1.$2-$3-$4.$5"; $res = preg_replace($pattern_src, $pattern_rpl, $str); //$res eq 12.3ab-c5-67.8 way complicated since user need define $pattern_src , $pattern_rpl. if string vary in length, more complex explain. yes, write function/parser builds required regular expressions based on simple user pattern %%.%%%-%%-%%.%. wonder if there "built in" way achieve php? thinking sprintf etc., doesn't seem trick. ideas? ...

this follow question undefined reference rsa_generate_key in openssl? have openssl program generate rsa key, follows : #include <stdio.h> #include <openssl/rsa.h> #include <openssl/pem.h> int main(int argc, char* argv[]) { rsa *r = null; int ret; r = rsa_new(); bignum *bne = null; ret = rsa_generate_key_ex(r, 2048, bne, null); return 0; } when compile gcc -i../include rsatest.c -lcrypto -l. i undefined reference errors functions in libraries gdi32 , zlib. so correct this, have add -lz , -lgdi32, as gcc -i../include/ rsatest.c -lcrypto -lz -lgdi32 -l. my question is, aren't static libcrypto , libssl self sufficient? in why having add libraries make work? there option should have added while compiling library prevent this? i'm using 64 bit windows mingw compiler. made openssl library of msys , make.
