下载地址: https://www.php.net/downloads.php 1、wget下载php源码至/usr/local/src 下 wget https://www.php.net/distributions/php-7.3.8.tar.bz2 2、解压php-7.3 tar -zxvf php-7.3.8.tar.bz2 3.进入php-7.3文件夹中 ./configure  在linux中安装源码,在源码目录下使用 ./configure --prefix=xxx --with=xxx   其中configure是一个可执行脚本, --prefix 选项就是配置安装的路径,如果不配置该选项,安装后可执行文件默认放在/usr/local/bin,库文件默认放在/usr/local/lib,配置文件默认放在/usr/local/etc,其它的资源文件放在/usr/local/share,比较分散; --with选项为指定依赖. 4、可能出现的报错 libxml2 not found. Please check your libxml2 installation. 直接yum安装libxml2插件 yum install -y libxml2 (yum install -y libxml2-devel) 5、编译 make && make install 6、测试 例子:

Need to pull 2 nodes and combine the information in LibXML

生来就可爱ヽ(ⅴ<●) 提交于 2019-12-02 10:53:03
问题 I have an problem I could sure use some help with. First, be gentle. I am new to both perl and LibXML. I have been parsing a document and placing elements into an array that is then written to a speadsheet column. Durring testing it was discovered that some nodes have more than one child node of the same name. I need to combine the text from each of these child nodes into one element of the array. The (very simplified) format of the xml is: <Group> <title> <description> <reference> <fixtext>

libxml2: xpath relative to sub node

问题 Given the xml file <a> <b> <d>v</d> </b> <c> <d>v</d> </c> </a> And the xpath "//d/text()" I want to apply the xpath only to c and not to the whole document. This has to work with libxml2 2.7.6 Doing this does not work; xmlNodePtr node = <node pointer to c> xmlXPathContextPtr xpathCtx = xmlXPathNewContext( node->doc ); xpathCtx->node = node; xmlXPathObjectPtr xpathObj = xmlXPathEvalExpression ( "//d/text()", xpathCtx); Returned xpathObj contains refences to both /a/b/d and /a/c/d. Only /a/c/d

libxml2 preserve empty tags

假装没事ソ 提交于 2019-12-02 00:07:07
问题 libxml2 (for C) is not preserving empty elements in their original form on a save. It replaces <tag></tag> with <tag/> which is technically correct but causes problems for us. xmlDocPtr doc = xmlParseFile("myfile.xml"); xmlNodePtr root = xmlSaveFile("mynewfile.xml", doc); I've tried playing with the various options (using xlmReadFile ) but none seem to affect the output. One post here mentioned disabling tag compression but the example was for PERL and I've found no analog for C. Is there an
