的libxml的xmlNodePtr原始XML字符串？ [英] libxml xmlNodePtr to raw xml string?

问题描述

给定一个有效的，任意的xmlNodePtr，我想重新串节点的presentation，包括标签，属性和孩子在相同的形式（递归）。

Given a valid, arbitrary xmlNodePtr, I would like the string representation of that node, including the tag, attributes, and children in the same form (recursive).

FWIW，我的情况是我使用PerformXPathQuery从现有的文件中获取数据块。我需要查询的，这嵌套在它的XML元素，作为原始字符串的结果，这样我就可以将其插入一个文本字段。

FWIW, my scenario is I am using PerformXPathQuery to get a block of data from within an existing document. I need to get the results of the query, which has nested XML elements in it, as the raw string, so I can insert it into a text field.

这似乎是一个简单的任务，但是我无法找到一个简单的方法。写一个xmlDocPtr到文件必须做到这一点，但是，我看不到一个方便的方法，将做同样的事情在树的任意节点，并在内存中返回。

These seems like a simple task, however I cannot find an easy way. Writing an xmlDocPtr to file must do this, however, I cannot see a handy method that will do the same thing to an arbitrary node in the tree, and return it in memory.

我希望我只想从棕色的棕色文件的配色方案在盲xmlsoft.org

I hope I am just going blind from the brown-on-brown documentation color scheme at xmlsoft.org
