It only requires one function call to array_splice : $original = array( 'a', 'b', 'c', 'd', 'e' ); $inserted = array( 'x' ); // Not necessarily an array array_splice( $original, 3, 0, $inserted ); // splice in at position 3 // $original is now a b c x d e 回答2: A function that can insert at both integer and string positions: /** * @param array $array * @param int|string $position * @param mixed $insert

This means that (since I'm using Fragments) 2 Fragments are loaded. One of them being unnecessary... Here's my code: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // Determine which bundle to use; either the saved instance or a bundle // that has been passed in

XSLT 1.0 Using position() in <xsl:for-each> and <xsl:template>

匿名 (未验证) 提交于 2019-12-03 01:45:01
可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: My understanding is that the usage of <xsl:template /> and <xsl:for-each> almost serve the same purpose and <xsl:for-each > is a sort of "anonymous inline template" . Question: However, considering the below scenario, i think using <xsl:for-each> is more appropriate. Please validate my understanding, or is there a way the output can be achieved through <xsl:template> as well?
